What drives a normal relation between T-CD4 and T-CD8?

What drives a normal relation between T-CD4 and T-CD8?

Methods Patients with a proven inversion of CD4/CD8 ratio before the beginning of antiretroviral treatment and who, in the last five years, re-inverted to a normalized ratio (above one) in at least two consecutive estimations were eligible. Variables analyzed included: gender, age, former opportunistic infections, CD4+ nadir, viral load, length of antiretroviral therapy and therapeutic regime. ...

Numerical status of CD4+CD25+FoxP3+ and CD8+CD28- regulatory T cells in multiple sclerosis

Objective(s): Regulatory T cells, including CD4+CD25+Fox3+ and CD8+CD28- cells play an important role in regulating the balance between immunity and tolerance. Since multiple sclerosis is an inflammatory autoimmune disease, regulatory T cells are considered to be involved in its pathogenesis. In this study, we investigated the circulatory numbers of the two mentioned types of regulatory T cells...

Comparison of CD4+ and CD8+ T- lymphocyte in Helicobacter pylori-negative functional dyspepsia

Irradiated β-glucan enhances immune response to bacterial infection through CD4 and CD8 T-lymphocytes

Background: &beta-glucans are glucose polymers with a variety of stimulatory effects on the immune system. The objective of this study was to evaluate the immune-enhancing activities of low molecular weight gamma irradiated &beta-glucan (I&beta-g) extracted from Pleurotus ostreatus in response to Pseudomonas aeruginosa infection in rats. Materials and Methods: &beta-glucan (&beta-g) powder was ...

CD4 T cell-dependent CD8 T cell maturation.

We have investigated the contribution of CD4 T cells to the optimal priming of functionally robust memory CD8 T cell subsets. Intranasal infection of CD4 T cell-deficient (CD4(-/-)) mice with lymphocytic choriomeningitis virus resulted in the elaboration of virus-specific CD8 T cell responses that cleared the infection. However, by comparison with normal mice, the virus-specific CD8 T cells in ...
