CXCR4, a chemokine receptor known as Fusin or CD184, spans the outer membrane of various human cells, including leukocytes. This receptor is essential for HIV infection as well as for many vital cellular processes and is implicated to be associated with multiple pathologies, including cancers. This study employs various computational tools to inves...

Toxoplasma gondii is an intracellular protozoan parasite that causes toxoplasmosis in around one-third of the world population, particularly in pregnant women and immunocompromised individuals. Diabetes mellitus (DM) is one of the most severe global health challenges in the 21st century, and especially, type-2 diabetes mellitus (T2DM) accounts for...

Toxoplasma gondii (T. gondii) is an intracellular protozoan parasite that causes the disease Toxoplasmosis. Acute infection of T. gondii in pregnant women is dangerous because the parasite can transmit into developing foetus and can cause congenital toxoplasmosis. To assess the prevalence of T. gondii infection, its association with pregnancy and t...

Toxoplasmosis is one of the most prevalent infectious disease around the globe and it is caused by the parasite named Toxoplasma gondii. Infections normally lead to asymptomatic parasite persistence in immunocompetent warm-blooded hosts, including up to 30-50% of humans. However, T. gondii infection has also a major medical concern and can lead to...

Isocitrate dehydrogenase (IDH) isoform 1 (IDH1) and isoform 2 (IDH2) genes code for proteins that play important roles in the decarboxylation of isocitrate to α-ketoglutarate. Somatic mutations in the IDH1 and IDH2 genes are prognostically significant in patients with glioma and acute myeloid leukemia. However, very little is known about the germli...

Enterobacteriaceae are important human pathogens that cause many food and waterborne illness. Rapid emergence of multi-drug resistant bacteria in Bangladesh has become a serious problem. Phage-host interaction is now considered as the major driving force for the conversion of non-pathogenic bacteria to pathogenic ones. Evolution of highly pathogeni...

Toxoplasma gondii is an intracellular, zoonotic protozoan parasite that causes toxoplasmosis. It can potentially infect almost all mammalian and avian hosts including one-third of the human population world-wide. The major target group of the parasite includes immunocompromised patients (e.g. AIDS, cancer, organ transplantation) and fetus bearing p...

The unicellular parasite Toxoplasma gondii infects warm-blooded animals and humans, and it is highly prevalent throughout the world. Infection of immunocompetent hosts is usually asymptomatic or benign but leads to long-term parasite persistence mainly within neural and muscular tissues. The transition from acute primary infection towards chronic t...

Human immunodeficiency virus (HIV) possesses a major threat to the human life largely due to the unavailability of an efficacious vaccine and poor access to the antiretroviral drugs against this deadly virus. High mutation rate in the viral genome underlying the antigenic variability of the viral proteome is the major hindrance as far as the antibo...

Typhoid fever is one of the major health problems in Bangladesh. It is caused by the bacterium Salmonella enterica serovar Typhi (S. Typhi). S. Typhi is a highly virulent host restricted invasive pathogen that affects only humans. It remains an important cause of enteric disease in children in developing countries. It is estimated that more than 33...

Functional food can be either natural or processed. Food contains known biologically active compounds, which provides clinically proven and documented health benefit. So far, no database is available in Bangladesh regarding the functionality of the indigenous foods. As a primary step, this study had been conducted with an aim to identify and charac...

Cancer is clearly the most deadly disease in the developed world as one in three people develop cancer during their lifetime. The cure for cancer is like the Holy Grail since most of the existing treatments are not effective enough to provide full protection from this disease. In recent years the burgeoning of sophisticated genomic, proteomic and b...

Induction of HIV-1 specific CTL responses largely depends upon the presentation of CTL epitopes to the CD8+ T cells aided by a large number of different HLA class I alleles. Although several studies showed the clustering pattern of HIV-1 CTL epitopes, the underlying reason for this tendency remains unresolved. Moreover the hypothesis that the CTL e...

Thalassemia and other structural haemoglobinopathies are the major erythrocyte formation disorder prevalent in certain parts of the world including Bangladesh. We investigated 600 cases of anaemic patients referred from various parts of the country for diagnosis and counselling during 3 months (April to June 2011) of time. The most common form of h...

Beta thalassemia major is an inherited disease resulting from reduction or total lack of beta globin chains. Patients with this disease need repeated blood transfusion for survival. This may cause oxidative stress and tissue injury due to iron overload, altered antioxidant enzymes, and other essential trace element levels. The aim of this review is...

Vibrio cholerae O1 is a noninvasive enteric pathogen and serves as a model for studies of mucosal immunity. Although symptomatic V. cholerae infection induces durable protection against subsequent disease, vaccination with oral killed whole-cell V. cholerae stimulates less long-lasting protection against cholera. In this study, we demonstrated that...

Salmonella enterica serotype Typhi is a human-restricted intracellular pathogen and the cause of typhoid fever. Cellular immune responses are required to control and clear Salmonella infection. Despite this, there are limited data on cellular immune responses in humans infected with wild type S. Typhi. For this work, we used an automated approach t...
