Critical Loss of the Balance between Th17 and T Regulatory Cell Populations in Pathogenic SIV Infection
Chronic immune activation and progression to AIDS are observed after SIV infection in macaques but not in natural host primate species. To better understand this dichotomy, we compared acute pathogenic SIV infection in pigtailed macaques (PTs) to non-pathogenic infection in African green monkeys (AGMs). SIVagm-infected PTs, but not SIVagm-infected AGMs, rapidly developed systemic immune activat...
متن کاملExpansion of CD4+CD25+FoxP3+ Regulatory T Cells in Chronic Hepatitis C Virus Infection
Background: Regulatory T cells (Tregs) have been involved in impaired immunity and may have a pivotal role in persistence of viral infections. Objective: To develop a simple and reliable in-house three color flow cytometery of peripheral blood to understand the role of HCV infection in the increase of Tregs. Methods: The level of naturally occurring CD4+CD25+FoxP3+ regulatory T cells (nTregs) i...
متن کاملInactivated Mycobacterium phlei inhalation ameliorates allergic asthma through modulating the balance of CD4+CD25+ regulatory T and Th17 cells in mice
Objective(s): Th2 response is related to the aetiology of asthma, but the underlying mechanism is unclear. To address this point, the effect of nebulized inhalation of inactivated Mycobacterium phlei on modulation of asthmatic airway inflammation was investigated. Materials and Methods: 24 male BALB/c mice were randomly divided into three groups: control group (Group A), asthma model group (G...
متن کاملLoss of Circulating CD4 T Cells with B Cell Helper Function during Chronic HIV Infection
The interaction between follicular T helper cells (TFH) and B cells in the lymph nodes and spleen has a major impact on the development of antigen-specific B cell responses during infection or vaccination. Recent studies described a functional equivalent of these cells among circulating CD4 T cells, referred to as peripheral TFH cells. Here, we characterize the phenotype and in vitro B cell hel...
متن کاملDifferential transform method for a a nonlinear system of differential equations arising in HIV infection of CD4+T cell
In this paper, differential transform method (DTM) is described and is applied to solve systems of nonlinear ordinary differential equations which is arising in HIV infections of cell. Intervals of validity of the solution will be extended by using Pade approximation. The results also will be compared with those results obtained by Runge-Kutta method. The technique is described and is illustrat...
