ABSTRACT
Background: Rheumatoid arthritis is an autoimmune disease that gradually
destroys the synovial joints and leads to chronic inflammation. This autoimmune
disorder is associated with an increase in stress-related symptoms, including
anxiety and depression, and a decrease in social behaviors, which severely
reduces the patient's quality of life. Previous studies show that higher physical
activity during adolescence may lead to a decrease in neurobehavioral disorders
in adulthood. This study was conducted with the aim of evaluating the increase
of physical activity from early adolescence on stress-related behaviors and
inflammation in mice with rheumatoid arthritis.
Methods: Male mice were randomly exposed to a running wheel from early
adolescence to adulthood, and then rheumatoid arthritis was induced. Stress-
related behaviors, including anxiety, depression and social behavior were
investigated in animals. The level of interleukin 17 (IL-17) and interferon
gamma (IFN-γ) were also measured as important inflammatory markers in the
serum.
Results: The results showed that physical activity from early adolescence
significantly resulted in decreased stress in mice with rheumatoid arthritis. In
addition, the running wheel led to a decrease in the levels of (IL-17) and (IFN-γ)
in rheumatoid arthritis-induced mice as two important indicators of
inflammation.
Conclusion: This study shows that increased physical activity during
adolescence to adulthood may make mice resistant to increased stress and
inflammation caused by rheumatic arthritis.

Extended Abstract
Background: Rheumatoid arthritis is one of
the most common chronic autoimmune
inflammatory diseases. Due to its chronic,
painful and debilitating nature, this disease
has profound effects on quality of life.
Rheumatoid arthritis is associated with stress-
related disorders such as anxiety and
depression, with an estimated prevalence of
14% for anxiety and 16.8%38.8% for
depression. Inflammatory factors such as
interleukin 17 (IL-17) and interferon- gamma
(IFN-γ) play a key role in the pathogenesis
and progression of rheumatoid arthritis. On
the other hand, there is a close relationship
between increased levels of IL-17 and IFN-γ
and stress-related disorders. During the last
few years, studies have shown that physical
activity and exercise as a non-
pharmacological solution to reduce stress in
humans and animals. However, their effects
on the condition of rheumatism have not been
fully determined. In this study, we aimed to
investigate the effect of physical activity
during adolescence to adulthood, which is a
very important period in brain development,
on the vulnerability of animals to stress-
related disorders and inflammation in mice
with rheumatoid arthritis.
Methods: Male BALB/c mice weighing 10-
11 grams (age 21 days) were kept in a quiet
room with a light-dark cycle of 12.12 hours
and standard conditions (temperature:
23.5±0.5 °C, humidity: 50-40%) and had free
access to food and water. Forty adolescent
mice were divided into 4 groups: healthy;
rheumatoid arthritis, exercise, and rheumatoid
arthritis+exercise. There were 10 mice in
each group. To perform physical activity,
exercise groups were exposed to a running
wheel from the age of 21 to 90 days. Two
adolescent male mice were housed in a
partitioned cage without physical contact, and
each animal had free access to a running
wheel. To induce rheumatoid arthritis, ten
days after stopping exercise, at the age of 100
and subsequently at 113 days, the animals
received type II collagen emulsion and
adjuvant subcutaneously. Healthy groups
received only vehicle. From the 10th day
after the first immunization, the development
of clinical symptoms was confirmed through
the increase in the thickness of the paw and
the joint of the right hind leg. The animals did
not exercise after inducing the disease. To
measure stress-related disorders, animals
were exposed to three behavioral tests
including an elevated plus maze (at the age of
127), a social interaction test (at the age of
129), and a forced swimming test (at the age
of 132). After completing the behavioral
tests, the mice were deeply anesthetized by a
combination of ketamine and xylazine. Then
blood was taken from the heart and the serum
was collected to measure IL-17 and IFN-γ
using the ELISA technique. Data were
analyzed using SPSS software version 26
under two-way analysis of variance. Tukey's
post hoc test was used for multiple
comparisons. The data are presented as
meastandard error of the mean and p<0.05
was considered significant.
Results: Elevated plus maze, for the time
spent in the open arm, the analysis showed a
main effect of exercise (p=0.019) and
rheumatism (p<0.001), there was also a
significant interaction (p=0.004) between
exercise and rheumatism. In addition, for the
number of open arm entries, the analysis
showed a main effect of exercise (p=0.033)
and rheumatism (p<0.001), there was also a
significant interaction (p=0.004) between
exercise and rheumatism. Tukey's post hoc
test revealed that the induction of rheumatism
led to a decrease in the amount of time spent
(p<0.001) and the number of entries
(p<0.001) in the open arm compared to the
healthy mice. In addition, exercise in mice
with rheumatism led to a reduction in stress
by increasing the amount of time spent
(p<0.001) and the number of entries
(p<0.001) in the open arm compared to the
rheumatism group. Social behavior test, the
analysis showed a main effect of exercise
(p=0.037) and rheumatism (p<0.001), and an
interaction between exercise and rheumatism
(p=0.02) in the social interaction test. Tukey's
post hoc test showed that the induction of
rheumatism decreased the interaction time

(p<0.001) in mice compared to the healthy
group. In addition, exercise increased social
behavior by increasing the interaction time
(p<0.001) in mice with rheumatism compared
to the rheumatism group. Forced swimming
test, the analysis revealed a main effect of
exercise (p=0.009) and rheumatism
(p<0.001). However, there was no significant
interaction between exercise and rheumatism
(p<0.05). Tukey's post hoc test indicated that
the induction of rheumatism increased
immobility time (p<0.01) in mice compared
to the healthy group. On the other hand,
exercise increased the level of immobility
time (p<0.05) and decreased stress in mice
with rheumatism compared to the rheumatism
group. These findings mean that exercise
from early adolescence can increase the
resistance of adult mice against stress-related
behaviors induced by rheumatism. Statistical
analysis of cytokine results showed a main
effect of exercise (p=0.011) and rheumatism
(p=0.001), and also a significant interaction
between exercise and rheumatism (p=0.001)
for IL-17. In addition, for IFN-γ, the analysis
revealed a main effect of exercise (p<0.001)
and rheumatism (p<0.001), there was also a
significant interaction between exercise and
rheumatism (p<0.001). Tukey's post hoc test
showed that the induction of rheumatism
resulted in a significant increase in both
cytokines IL-17 (p<0.001) and IFN-γ
(p<0.001) in serum compared to the healthy
mice. In addition, exercise decreased
inflammation in mice with rheumatism by
decreasing the amount of IL-17 (p<0.01) and
IFN-γ (p<0.001) in the serum compared to
the rheumatism group. This means that
exercise from early adolescence can increase
the resistance of adult mice against the
increase of inflammation caused by the
induction of rheumatism.
Conclusion: In the present study, the findings
showed that increasing physical activity as an
exercise strategy may play a role in reducing
the level of stress-related disorders in mice
suffering from rheumatism by reducing the
level of IL-17 and IFN-γ. Considering this
point that recent studies have shown that
exercise has beneficial effects on rheumatism
symptoms, these results can be approached as
an initial step to start clinical studies in the
future.

Background Exercise is advocated in the treatment of rheumatoid arthritis (RA). However, uncertainty around the acute effects of exercise on pain and inflammation may be stopping people with RA from exercising more regularly. Objectives To determine the acute effects of exercise on pain symptoms, clinical inflammatory markers, and inflammatory cytokines in RA. Design A systematic review of the literature. Data sources and methods Five databases were searched (PubMed, Cochrane Library, CINAHL, Scopus and SPORTDiscus); inclusion criteria were studies with acute exercise, a definite diagnosis of RA and disease characteristics assessed by clinical function (i.e., disease activity score, health assessment questionnaire and self-reported pain), clinical markers associated with inflammation (i.e., c-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)), and inflammatory cytokines (i.e., interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-α)). Results From a total of 1544 articles, initial screening and full text assessment left 11 studies meeting the inclusion criteria. A total of 274 people were included in the studies (RA = 186; control = 88). Acute bouts of aerobic, resistance, and combined aerobic and resistance exercise did not appear to exacerbate pain symptoms in people with RA. Conclusion Post-exercise responses for pain, clinical inflammatory markers and inflammatory cytokines were not different between people with or without RA. Exercise prescription was variable between studies, which limited between-study comparisons. Therefore, future investigations in people with RA are warranted, which combine different exercise modes and intensities to examine acute effects on pain symptoms and inflammatory markers.

Type 2 diabetes is a risk factor for the development of cognitive impairment. Increasing evidence suggests that regular exercise is beneficial for the treatment of clinical symptoms in diabetic patients. The current study aimed to evaluate whether increasing physical activity through swimming training can reduce memory impairment in an animal model of type 2 diabetes. Diabetes and non-diabetes mice underwent swimming training for four weeks, and then working, spatial, and recognition memory were evaluated using three behavioral tests. Body weight, glucose, and insulin resistance were monitored. We also measured inflammatory cytokines (interleukin (IL)-6, IL-1β, and tumor-necrosis-factor (TNF)-α), an anti-inflammatory cytokine (IL-10), and brain-derived-neurotrophic-factor (BDNF), and glutamate levels in the hippocampus or prefrontal cortex of mice. The findings showed that diabetes increased body weight, glucose, and insulin resistance, impaired working, spatial and recognition memory, increased levels of IL-6, IL-1β, TNF-α, and glutamate levels, and decreased BDNF in the hippocampus of diabetic mice. While higher physical activity was associated with reduced body weight, glucose, and insulin resistance, attenuated memory impairment, IL-6, IL-1β, TNF-α, and glutamate, and increased BDNF levels in the hippocampus and prefrontal cortex of diabetic mice. This study shows that swimming training can normalize body weight and glucose-insulin axis and reduce inflammation and glutamate in the hippocampus and enhance the neurotrophic system in both the hippocampus and prefrontal cortex of diabetic mice. This study also suggests that higher physical activity through swimming training can improve cognitive impairment in a mouse model of type 2 diabetes.

Valproic acid (VPA) treatment during pregnancy is a risk factor for developing autism spectrum disorder, cognitive deficits, and stress-related disorders in children. No effective therapeutic strategies are currently approved to treat or manage core symptoms of autism. Active lifestyles and physical activity are closely associated with health and quality of life during childhood and adulthood. This study aimed to evaluate whether swimming exercise during adolescence can prevent the development of cognitive dysfunction and stress-related disorders in prenatally VPA-exposed mice offspring. Pregnant mice received VPA, afterwards, offspring were subjected to swimming exercise. We assessed neurobehavioral performances and inflammatory cytokines (interleukin-(IL)6, tumor-necrosis-factor-(TNF)α, interferon-(IFN)γ, and IL-17A) in the hippocampus and prefrontal cortex of offspring. Prenatal VPA treatment increased anxiety-and anhedonia-like behavior and decreased social behavior in male and female offspring. Prenatal VPA exposure also increased behavioral despair and reduced working and recognition memory in male offspring. Although prenatal VPA increased hippocampal IL-6 and IFN-γ, and prefrontal IFN-γ and IL-17 in males, it only increased hippocampal TNF-α and IFN-γ in female offspring. Adolescent exercise made VPA-treated male and female offspring resistant to anxiety-and anhedonia-like behavior in adulthood, whereas it only made VPA-exposed male offspring resistant to behavioral despair, social and cognitive deficits in adulthood. Exercise reduced hippocampal IL-6, TNF-α, IFN-γ, and IL-17, and prefrontal IFN-γ and IL-17 in VPA-treated male offspring, whereas it reduced hippocampal TNF-α and IFN-γ in VPA-treated female offspring. This study suggests that adolescent exercise may prevents the development of stress-related symptoms, cognitive deficits, and neuroinflammation in prenatally VPA-exposed offspring mice.

Background Depression is the most common comorbidities associated with rheumatoid arthritis (RA). We aimed to explore the mechanism of association between RA and depression. Methods 120 subjects were enrolled and depression was diagnosed and assessed using DSM-5 and 24-item version of Hamilton Depression Scale. Pain intensity and joint function in patients with RA were assessed using the visual analogue scale (VAS) and health assessment questionnaire (HAQ). Serum levels of interferon-gamma (IFN-γ), indoleamine 2,3-dioxygenase (IDO), kynurenine (KYN), tryptophan (TRP), and quinolinic acid (QUIN)were detected. In animal experiments, K/BxN mice with RA-like phenotype was used and depressive behavior was observed. The protein expression level of N-methyl -D- aspartate receptor 2B (NR2B) in the hippocampus was detected. Results In this study, 36.67% of patients with RA also had depression. The working status, month family income, tender joint count, the VAS and HAQ score were the main factors influencing the depression in RA patients. HAQ score was found to be an independent risk factor for depression in RA. Serum IDO, IFN-γ, KYN were increased and TRP contents were decreased in RA group. K/BxN mice with RA-like phenotype showed depressive behavior. However, injection of IFN-γ neutralizing antibody could inhibit kynurenine pathway and reverse the depressive behavior in mice. The levels of QUIN in the neurotoxic metabolic pathway were increased and N-methyl -D- aspartate receptors (NMDAR) were activated, which may be the mechanism behind the onset of depression. Conclusions From clinical and preclinical aspects, the occurrence of depression in RA was explored and the related mechanism was revealed.

Pregnancy is a very complex and highly stressful time in which women become more physically and emotionally vulnerable. Therefore, mothers are more likely to face decreased self-esteem and increased postpartum depression. Despite the high prevalence of postpartum depression, more than 50% of mothers are undiagnosed or untreated, showing an urgent need to explore an effective preventive strategy. A healthy lifestyle and regular physical activity have been suggested to be associated with an increased quality of life in pregnant and postpartum women. The purpose of this study was to determine whether swimming exercise before and during pregnancy can affect maternal care and postpartum depression-related behaviors in dams. To this end, female NMRI and C57BL/6 J mice were subjected to swimming exercise before conception and throughout pregnancy. On postpartum days 1-2, maternal behavior including nest building, active nursing, and licking/grooming were monitored. A battery of behavioral tests was also used to measure depression-related symptoms including anhedonia- and anxiety-like behavior, social behavior, and behavioral despair. To identify the underlying mechanisms, corticosterone and inflammatory cytokines during late pregnancy, and corticosterone and brain serotonin during the postpartum period were measured in dams. The findings indicated that swimming exercise increased gestational corticosterone, decreased maternal care and brain serotonin, and increased all depression-related behaviors in postpartum C57BL/6 J dams, while only increased licking/grooming and social behavior, and reduced anhedonia-like behavior in postpartum NMRI dams. Taken together, this study suggests that swimming exercise before and during pregnancy could alter maternal care and postpartum depression-like behavior in a strain-dependent manner.

A growing body of evidence suggests voluntary physical activity is associated with decreased stress-related disorders such as anxiety- and depression-like behaviours in both humans and rodents. The postpartum period is also a vulnerable transition time for the development of these neurobehavioural disorders in women. This study aimed to determine whether voluntary physical activity during pregnancy and postpartum periods can increase maternal care and decrease anxiety- and depression-related behaviours in postpartum dams. To this end, pregnant mice were exposed to running wheel during their gestational and postpartum periods, and then nest building, active nursing, and licking/grooming behaviours were recorded as maternal care. To assess depression and anxiety-related symptoms, several behavioural tests such as the novelty-suppressed feeding test, tail suspension test, sucrose preference test, social interaction test, forced swim test, open field, elevated plus maze, light-dark box, and elevated zero maze were used. To identify the most important mechanisms behind these behavioural alterations, we measured oxytocin, adrenocorticotropic hormone (ACTH) and corticosterone in the serum and serotonin in the brain of postpartum dams. Our findings showed that running wheel significantly increased maternal care, and decreased depression-like behaviour during the postpartum period through increasing serum oxytocin and brain serotonin levels, whereas it decreased anxiety-like behaviour via attenuating the hypothalamic-pituitary-adrenal (HPA) axis activity by measuring ACTH and corticosterone levels in postpartum dams. Overall, this study suggests that voluntary physical activity during pregnancy and the postpartum period might improve maternal care and decrease anxiety and depression-related behaviours in postpartum dams.

Alzheimer's disease (AD) is associated with increased depression-related behaviours. Previous studies have reported a greater risk of AD and depression in women. In recent years, we and others have provided evidence that exercise during life could be used as a therapeutic strategy for stress-related disorders such as depression. The main goal of the current study was to determine whether treadmill exercise during life can reduce depression-related behaviours in male and female Wistar rats with sporadic Alzheimer-like disease (ALD). Animals were subjected to treadmill exercise eight weeks before and four weeks after ALD induction by streptozocin (STZ). We measured body weight, food intake, and depression-related symptoms in rats using five behavioural tests. We measured brain-derived-neurotrophic-factor(BDNF), tumour-necrosis-factor (TNF)-α, and interleukin(IL)-10 levels in the hippocampus and prefrontal cortex of animals. Our findings showed that exercise but not ALD induction decreased body weight and food intake in male and female rats. ALD induction increased depression-related symptoms and hippocampal TNF-α in male and female rats. Besides, treadmill exercise alone decreased depression-related behaviours and increased hippocampal BDNF in females but not males. We also found that treadmill exercise decreased depression-related behaviours and TNF-α in the hippocampus and prefrontal cortex, and increased IL-10 in the prefrontal cortex and BDNF in the hippocampus of female ALD-induced rats. However, treadmill exercise only reduced anhedonia-like behaviour and hippocampal TNF-α in male ALD-induced rats. Overall, the evidence from this study suggests that treadmill exercise alters depression-related behaviours, brain BDNF and cytokines in a sex-dependent manner in rats with sporadic Alzheimer-like disease.

New findings: What is the central question of this study? Can swimming exercise decrease depression-like behaviour and inflammation in type 2 diabetic mice? What is the main finding and its importance? This study demonstrates that swimming exercise decreased depression-like behaviour by reducing inflammation in type 2 diabetic mice. This study suggests that swimming exercise might be useful for the treatment of depression-related disorders in patients with type 2 diabetes. Abstract: Clinical and experimental studies have shown that type 2 diabetes is associated with depression-related disorders. Inflammation has been identified as a common mechanism in both type 2 diabetes and depression. Several studies have suggested that swimming exercise might be able to reduce depression-related symptoms. The present study aimed to explore whether swimming exercise can decrease depression-like behaviour in type 2 diabetic mice. To induce type 2 diabetes, male C57BL6 mice were treated with a high-fat diet and streptozocin. Type 2 diabetic animals were subjected to swimming exercise for four weeks. Then, depression-like behaviours were evaluated by sucrose preference, novelty-suppressed feeding, social interaction, and tail suspension tests. We also measured levels of glucose, insulin and pro-inflammatory cytokines such as interleukin (IL)-1β and tumour necrosis factor (TNF)-α in the serum of animals. The results indicated that type 2 diabetes significantly increased anhedonia- and depression-like behaviours in mice. We also found significant increases in glucose, insulin, and inflammatory cytokines in diabetic mice. Moreover, swimming exercise reduced anhedonia- and depression-like behaviour in type 2 diabetic mice. Swimming exercise also decreased glucose and inflammatory cytokines in the serum of mice with type 2 diabetes. Collectively, this study demonstrates that swimming exercise decreased depression-like behaviour by reducing inflammation in type 2 diabetic mice. Further clinical studies are needed to validate these findings in patients with type 2 diabetes. This article is protected by copyright. All rights reserved.

Anxiety-related behaviors are among the most prevalent psychiatric disorders in patients with type 2 diabetes (T2D). The protective effect of exercise on neuropsychiatric disorders has been documented. However, there are no studies that examined whether swimming exercise can decrease anxiety-like symptoms in type 2 diabetes. We investigated the effects of swimming exercise on body weight, anxiety-like behavior, glucose and insulin levels, and brain oxidative stress in male C57BL/6 mice. T2D-induced mice were subjected to swimming exercise, then anxiety-like behaviors were measured by the open field, light-dark box, and elevated plus-maze tests. Glucose and insulin levels were measure in serum, and antioxidant/oxidative markers including glutathione (GSH), malondialdehyde (MDA), and glutathione disulfide (GSSG) were measured in the brain. Our findings showed that T2D increased body weight, anxiety-like symptoms, glucose and insulin resistance, and oxidative stress by increasing MDA and GSSG levels in the brain of mice. Interestingly, swimming exercise reversed these parameters in diabetic mice. Our findings clearly indicate that there is a protective impact of swimming exercise on anxiety-like behavior by reducing insulin resistance and brain oxidative stress in mice with type 2 diabetes. Further studies are needed to validate these findings in humans.

Depression is a psychiatric disorder with several comorbidities that has a complicated pathophysiology. Multiple mechanisms such as abnormal hypothalamic-pituitary adrenal (HPA) axis activity, neurotransmission (namely serotonin), and immune-inflammatory responses are involved in the pathophysiology of disease. In this study, we hypothesized that applying exercise (running wheel (RW) and treadmill (TM)) or fluoxetine (FLX) during adolescence could protect adult rats against the negative impact of early-life stress. To do this, we applied maternal separation stress (MS) to neonatal rats from postnatal day (PND) 2 to 14 and at PND 28, rats were divided into 8 experimental groups and were subjected to TM or RW or FLX treatment. After four weeks of physical activity or FLX treatment, at PND 64, behaviors were assessed by applying forced swimming test, sucrose preference test, open-field test, and elevated plus maze test. Serum cortiscosterone (CORT) levels and expression of genes associated with inflammatory factors (Il1β, Hmgb1, and Il6) and serotonergic systems (5-ht2c and 5-ht3a) were studies in the hippocampus (HIPP) and prefrontal cortex (PFC). Our results revealed that RW and FLX treatment during adolescence are capable of attenuating MS-induced depressive- and anxiety-like disorders in adult male rats. These effects were accompanied by the normalization of both serum CORT and the expression of genes in the HIPP and PFC. TM exercise in adolescence showed anxiolytic effects but failed to produce antidepressant-like effects. Results of this study suggest that voluntary physical activity during adolescence can reduce the negative effects of early-life stress through different mechanisms.
