Inefficient Immune Killer Cells Abet HIV Infection
Aim To estimate the prevalence of hazardous drinking and its socio-economic distribution among Russian men. Design Participants were an age-stratified, population-based random sample of men aged 25–54 years living in Izhevsk, a city in the Urals, Russia. Interviewers administered questionnaires to cohabiting proxy respondents about behavioural indicators of hazardous drinking derived from frequ...
متن کاملAdaptive Reconfiguration of Natural Killer Cells in HIV-1 Infection
Human cytomegalovirus (HCMV) co-infection is highly prevalent within HIV-1 cohorts and is an important cofactor in driving ongoing immune activation, even during effective antiretroviral treatment. HCMV infection has recently been associated with expansion of adaptive-like natural killer (NK) cells, which harbor epigenetic alterations that impact on their cellular function and phenotype. The in...
متن کاملNatural killer cells from HIV-1+ patients produce C-C chemokines and inhibit HIV-1 infection.
Human NK cells have been shown to produce cytokines (e.g., IFN-gamma and TNF-alpha) and the chemokine macrophage inflammatory protein (MIP)-1alpha following stimulation with the combination of two monokines, IL-15 plus IL-12. The C-C chemokines MIP-1alpha, MIP-1beta, and RANTES have been identified as the major soluble macrophage-tropic HIV-1-suppressive factors produced by CD8+ T cells, which ...
متن کاملHematopoietic Stem and Immune Cells in Chronic HIV Infection
Hematopoietic stem cell (HSC) belongs to multipotent adult somatic stem cells. A single HSC can reconstitute the entire blood system via self-renewal, differentiation into all lineages of blood cells, and replenishment of cells lost due to attrition or disease in a person's lifetime. Although all blood and immune cells derive from HSC, immune cells, specifically immune memory cells, have the pr...
متن کاملNatural killer cells and immune surveillance.
OBJECTIVES To analyze the importance of natural killer cells, their killer immunoglobulin-like receptors (KIR) and genes in autoimmunity and in the immune surveillance against infectious agents and stem cells transplantation. The characteristics and polymorphisms of the KIR genes and receptors in the Brazilian population is described. SOURCES Textbooks, review articles and recent scientific a...
