Human reproductive failure may be a consequence of aberrant expression of immunological factors during pregnancy. Although the relative importance of immunological factors in human reproduction remains controversial, substantial evidence suggests that human leukocyte antigens (HLA), antisperm antibodies, integrins, the leukaemia inhibitory factor (LIF), cytokines, antiphospholipid antibodies, e...
The clinical presentation of paracoccidioidomycosis is spectral. Spontaneous cure, state of latency or active disease with different levels of severity can occur after the hematogenous dissemination. The morphology and number of skin lesions will depend on the interaction of host immunity, which is specific and individual, and fungus virulence. Some individuals have natural good immunity, which...
Donor-recipient ABO blood group mismatching is associated with a decreased graft survival rate in liver transplantation. We have been unable to demonstrate an effect of high levels of panel reactive antibody or a positive donor-specific cytotoxic antibody cross-match on graft survival. A limited analysis of HLA-matching for the A, B, and DR loci suggests a paradoxical effect, but much more expe...
Despite advances in prevention and treatment of heart transplant rejection, development of cardiac allograft vasculopathy (CAV) remains the leading factor limiting long-term survival of the graft. Cardiac allograft vasculopathy etiopathogenesis is not fully understood, but a significant role is attributed to endothelial cell damage, caused by immunological and non-immunological mechanisms. Immu...
Hepatitis B virus (HBV) infection and its sequelae which include cirrhosis and hepatocellular carcinoma is a major public health problem throught the world.The WHO strategy for effective control of HBV infection is vaccination with the surface antigen of virus(HBsAg).The results obtained from a large number of studies demonstrated that the vaccine induces a protective antibody resonse (anti-HB...
Atopic dermatitis (AD) is a pruritic, relapsing, chronic disease that arises most commonly during infancy, childhood, or adolescence. It is clear that genetic factors are important in AD, a family history of AD, allergic rhinitis, and/or asthma and other “Atopic” phenomena being common in patient with AD. The two main pathogenetic characteristic of AD are: I) IgE-mediated antigen dependent “Spe...
The purpose of the review is to present an analysis current literature data on tumor immunology, effector mechanisms antitumor immunity, and prospects for development new immunotherapeutic approaches cancer treatment. Immunological surveillance intellectual basis idea immunology. No one doubts role immunological in protection against tumors. However, cells have a variety that allow them avoid a...
objective(s): according to the occupationally risk of infection in staff workers who have direct contact with mycobacterium species, we investigated their immunological parameters and compared with healthy purified protein derivative (ppd) negative volunteers. materials and methods : we investigated 20 ppd positive volunteers working at tuberculin unit of razi vaccine and serum research insti...
