Background: Beta-thalassemia major is one of the major health problems in our country. Many studies have confirmed the fact that, these patients have an increased susceptibility to bacterial infections. Objective: In this study, we have assessed the humoral immune system in 68 thalassemic patients by measuring their serum concentration of Immunoglobulin G (IgG), IgM, IgA, C3 and C4 in order to ...

People are generally unaware of the operation of the system of cognitive mechanisms that ameliorate their experience of negative affect (the psychological immune system), and thus they tend to overestimate the duration of their affective reactions to negative events. This tendency was demonstrated in 6 studies in which participants overestimated the duration of their affective reactions to the ...

Herpes zoster (Shingles; Zona) is an acute infectious skin disease that is caused by the reactivation of varicella zoster virus (VZV). After the initial infection (chickenpox) or vaccination, the virus remains inactive or latent in the dorsal root ganglia (DRG); when decreasing cell mediated immunity (CMI) occurs, the virus is reactivated from a latent phase to a lytic phase and frequently repl...

Human immunodeficiency virus type 1 (HIV-1) is the causative virus responsible for acquired immune deficiency syndrome (AIDS), for which there is still no protective vaccine. Since 1983, more than 34 million people have been infected with HIV across the world, with 1.5 million people dying as a result of complications from infection each year. HIV-1 virions mainly infect cells of the immune sys...

People may reach the upper limits of the human life span at least partly because they have maintained more appropriate immune function, avoiding changes to immunity termed "immunosenescence." Exceptionally long-lived people may be enriched for genes that contribute to their longevity, some of which may bear on immune function. Centenarian offspring would be expected to inherit some of these, wh...

Toxoplasmosis caused by Toxoplasma gondii is an asymptomatic disease, but often takes a severe and life-threatening course during pregnancy, in foetuses, new bon babies immune-compromised people.

conclusions the results of our study show that serum zinc level in bronchiectasis patients was lower than the control group and the difference was statistically significant. it seems that the use of zinc supplement can reduce progression of the infectious disease regarding its role in improving the immune system reactions and some unknown mechanisms. therefore, prophylactic and therapeutic use ...
