Gamma/Delta T-Cell Functional Responses Differ after Pathogenic Human Immunodeficiency Virus and Nonpathogenic Simian Immunodeficiency Virus Infections

Divergent CD4+ T memory stem cell dynamics in pathogenic and nonpathogenic simian immunodeficiency virus infections.

Recent studies have identified a subset of memory T cells with stem cell-like properties (T(SCM)) that include increased longevity and proliferative potential. In this study, we examined the dynamics of CD4(+) T(SCM) during pathogenic SIV infection of rhesus macaques (RM) and nonpathogenic SIV infection of sooty mangabeys (SM). Whereas SIV-infected RM show selective numeric preservation of CD4(...

Prevalence of Hepatitis B virus, Hepatitis C virus and human immunodeficiency virus infections among patients candidate for orthopedic trauma surgeries

Background: Infectious diseases are major public health problems, among which blood-borne ones are the most important infections. Patients who undergo orthopedic surgery are at higher risk of transmitting infectious diseases from and to others, due to repeated blood examinations and injection, drains secretion and receiving blood products. Accordingly, in this study we determined prevalence of ...

Distribution of Epstein-Barr Virus and Human Herpesvirus 8 Co-Infections among Human Immunodeficiency Virus -1 Positive Patients

Background and Aims: Among Human Immunodeficiency Virus (HIV)-infected individuals, Epstein-Barr virus (EBV) and Human Herpesvirus (HHV)-8 could cause significant illness as opportunistic infections. The purpose of the present study was to evaluate the prevalence of EBV and HHV-8 in saliva specimens obtained from HIV-1 infected Iranian individuals under the Highly Active Antiviral Therapy (HAAR...

Human Immunodeficiency Virus (HIV) and Cardiomyopathy: A Systematic Review

Human immunodeficiency virus (HIV) infection has been associated with cardiac disease, including anatomical or functional disturbance to the heart. Cardiomyopathy (CMP) is one of these disturbances that have been associated with high rates of morbidity and mortality. In this review article, several aspects of potential relationships between HIV infection and cardiomyopathy development have been...
