Estrogens act through nuclear and membrane-initiated signaling. Estrogen receptor alpha (ERα) is critical for reproduction, but the relative contribution of its nuclear and membrane signaling to the central regulation of reproduction is unclear. To address this question, two complementary approaches were used: estetrol (E 4 ) a natural estrogen act...
Olfactory communication is triggered by pheromones that profoundly influence neuroendocrine responses to
drive social interactions. Two principal olfactory systems process pheromones: the main and the vomeronasal or
accessory system. Prolactin receptors are expressed in both systems suggesting a participation in the processing
of olfactory infor...
En ocasión de los cincuenta años de vida como Universidad, el Departamento Editorial tuvo a bien sumarse a las actividades conmemorativas lanzando una convocatoria abierta, cuyo objetivo fue recoger un selecto muestrario de los frutos que ha dado la institución. En una primera instancia, la convocatoria permitía que cualquiera pudiese postular a la...
The neuroendocrine regulation of the seasonal reproductive axis requires the integration of internal and external signals to ensure synchronized physiological and behavioral responses. Seasonal reproductive changes contribute to intermittent production, which poses challenges for optimizing goat product yields. Consequently, a significant objective...
Reproduction represents one of the most important biological events for the organism due to its relevance in perpetuating life. It allows the production of offspring with similar characteristics to the progenitor. The behavioral events of reproduction comprise several changes that prepare the organisms and favor the display of specific behaviors. R...
Estrogens act through nuclear and membrane-initiated signaling. Estrogen receptor alpha (ERα) is critical for reproduction, but the relative contribution of its nuclear and membrane signaling is unclear. To address this question, we used two complementary approaches: estetrol (E4) a natural estrogen described to act as an agonist of nuclear ERα and...
Simple Summary
Exogenous glutamate administration to yearling-anestrous goats enhanced not only ovarian function (i.e., ovulation rate and antral follicle number) but also denoted undoubted effects at the hypothalamic-pituitary level, augmenting LH pulsatility. Our results show not only the use of glutamate as a clean alternative but also as an int...
Chronic kidney disease (CKD) is a multifactorial pathology that progressively leads to the deterioration of metabolic functions and results from deficient glomerular filtration and electrolyte imbalance. Its economic impact on public health is challenging. Mexico has a high prevalence of CKD that is strongly associated with some of the most common...
The onset of puberty is associated with the psychophysiological maturation of the adolescent to an adult capable of reproduction when olfactory signals play an important role. This period begins with the secretion of the gonadotropin-releasing hormone (GnRH) from GnRH neurons within the hypothalamus. This is regulated by kisspeptin neurons that exp...
Alterations in the sense of smell (dysosmia, anosmia, hyposmia) are frequently experienced by patients with chronic kidney disease. However, currently, the aetiology and consequences are poorly understood, with no effective treatments available to address such impairment. In general, the capacity of olfactory perception is affected in patients with...
Estrogens exert pleiotropic effects on multiple physiological and behavioral responses. Male and female sexual behavior in rodents constitutes some of the best characterized responses activated by estrogens in adulthood and largely depend on ERα. Evidence exists that nucleus‐ and membrane‐initiated estrogen signaling cooperate to orchestrate the ac...

Profound behavioral changes occur in the mother at parturition, a time when the maternal brain undergoes extensive remodeling of neural circuits, especially in olfactory structures. Adult neurogenesis, a form of brain plasticity, could constitute an adaptive response to motherhood. The present study hypothesized that chemical disruption of olfactor...
New neurons are continuously added to the main olfactory bulb (MOB) of the mammalian brain. While their function has been demonstrated in olfactory learning, it is less known in an ethological context such as mothering. We addressed this question by investigating whether in sheep mothers the adult-generated olfactory neurons contribute to the proce...
Estradiol (E2) is a key regulator of reproduction through its role on the feedback control of gonadotropin secretion by the hypothalamus. E2 effects are mainly mediated via estrogen receptor alpha (ERα) activation by a combination of the nuclear and the membrane-associated pathways. However, the contribution of these mechanisms to the regulation of...
Sexual behavior in rodents is modulated by the olfactory system. The olfactory bulb (OB) is a structure that undergoes continues neurogenesis in adulthood. We have previously shown that 15 days after males rats pace the sexual interaction and ejaculate 1 or 3 times, there is an increase in the density of new cells that reach the accessory olfactory...
We have previously demonstrated, that 15 days after female rats pace the sexual interaction, there is an increase in the number of new cells that reach the granular cell layer (GrL) of the accessory olfactory bulb (AOB). The aim of the present study was to evaluate, if the first sexual experience in the female rat increases cell proliferation in th...
We have previously shown that the first-paced mating encounter increases the number of newborn cells in the granule cell layer (Gra; also known as internal cell layer, ICL) of the accessory olfactory bulb (AOB) in the adult female rat (Corona et al., 2011). In the present study we evaluated if repetition of the stimulus (paced mating) could increas...
In rodents, sexual behavior depends on the adequate detection of sexually relevant stimuli. The olfactory bulb (OB) is a region of the adult mammalian brain undergoing constant cell renewal by continuous integration of new granular and periglomerular neurons in the accessory (AOB) and main (MOB) olfactory bulbs. The proliferation, migration, surviv...
Olfaction is the most relevant chemosensory sense of the rodents. General odors are primarily detected by the main olfactory system while most pheromonal signals are received by the accessory olfactory system. The first relay in the brain occurs in the olfactory bulb, which is subdivided in the main and accessory olfactory bulb (MOB/AOB). Given tha...
The ovarian hormones estrogen and progesterone are required for the complete display of sexual behavior in female rats. Paced mating produces a reward state in intact cycling and ovariectomized (OVX), hormonally primed females as evaluated by the conditioned place preference (CPP) paradigm. Most of the studies that have evaluated CPP induced by pac...
The continuous production and addition of new neurons during life in the olfactory bulb is well accepted and has been extensively studied in rodents. This process could allow the animals to adapt to a changing environment. Olfactory neurogenesis begins in the subventricular zone where stem cells proliferate and give rise to young undifferentiated n...
One way to evaluate sexual arousal is by measuring approach behavior to sexual incentive stimuli. In our case we measure approach behavior to an originally non-preferred compartment which is associated with the physiological state induced by mating. This change of preference indicative of a positive affective (reward) state can be evaluated by cond...

Hi,
Does anyone knows what kind of dye could I use to check where I put the electrode and did the recording (LFP)?. It has to be a dye that I could add during the recording and doesn´t affect the signal?.
Thanks in advance.
Best,
Rebeca
I found it difficult to dissolve it. We bought it in powder. Thanks in advance!
I´m looking for a kisspeptin antibody to stain kp neurons in mice tissue. Do you have any suggestions? I´ve tried the Anti-Kisspeptin Antibody from Merck (AB9754) and it works perfectly, but they are having problems producing it. Have you try any of the other available kisspeptin antibodies: from abcam, novusbio or bioss? or any other you may know/tried. I appreciate your help. Thanks.
