Mammalian immune system development depends on instruction from resident commensal microorganisms. Diseases associated with abnormal immune responses towards environmental and self antigens have been rapidly increasing over the last 50 years. These diseases include inflammatory bowel disease (IBD), multiple sclerosis (MS), type I diabetes (T1D), allergies and asthma. The observation that people...

host genetic factors play a central role in determining the clinical phenotype of human diseases. association between two polymorphic loci in human genome, human leukocyte antigen (hla) and killer cell immunoglobulin-like receptors (kirs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. hence, defining the influence of genetic di...

Abstract Many inflammatory and autoimmune diseases present with specific organ manifestations. Understanding the immune process at site of inflammation may offer important insights into novel therapeutic strategies. To this end, we established a biology platform that allows us to develop deep understanding human tissue Treg behavior enable next generation therapeutics aimed activating these reg...

immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. the immune rejection of male semen in the female reproductive tract is explained as the failur...

gene association studies are less appealing in cancer compared to autoimmune diseases. complexity, heterogeneity, variation in histological types, age at onset, short survival, and acute versus chronic conditions are cancer related factors which are different from an organ specific autoimmune disease, such as grave’s disease, on which a large body of multicentre data is accumulated. for years t...

Transgenics and gene targeting by homologous recombination provide an ideal opportunity to delineate immune functions of specific genes. These gene knockout mice are powerful tools to understand complex mechanism of immune system and molecular processes underlying autoimmune diseases and immunodeficiencies. Availability of an increased pool of genetically manipulated mice will provide a basic f...

To examine whether the ability of complement to form soluble immune complexes plays a role in preventing immune complex-mediated diseases, we analyzed the capacity of complement to inhibit immune precipitation (IIP) and to solubilize preformed immune aggregates (SOL) in 23 sera of patients with various hypocomplementemic states, and we correlated the results of these studies with the clinical s...
