Cd4+ T Cell Subsets during Virus Infection
To analyze the antiviral protective capacities of CD4(+) T helper (Th) cell subsets, we used transgenic T cells expressing an I-A(b)-restricted T cell receptor specific for an epitope of vesicular stomatitis virus glycoprotein (VSV-G). After polarization into Th1 or Th2 effectors and adoptive transfer into T cell-deficient recipients, protective capacities were assessed after infection with dif...
متن کاملMultiple CD4+ T cell subsets produce immunomodulatory IL-10 during respiratory syncytial virus infection.
The host immune response is believed to contribute to the severity of pulmonary disease induced by acute respiratory syncytial virus (RSV) infection. Because RSV-induced pulmonary disease is associated with immunopathology, we evaluated the role of IL-10 in modulating the RSV-specific immune response. We found that IL-10 protein levels in the lung were increased following acute RSV infection, w...
متن کاملCD4+FOXP3+ Regulatory T-Cell Subsets in Human Immunodeficiency Virus Infection
The role of CD4+FOXP3+ regulatory T cells (Treg) in human immunodeficiency virus (HIV) infection has been an area of intensive investigation and remains a matter of ardent debate. Investigation and interpretation suffered from uncertainties concerning Treg quantification. Firstly, Treg quantification and function in HIV infection remain controversial in part because of the lack of reliable and ...
متن کاملModulation of CD4+ T Cell Subsets by Euphorbia microciadia and Euphorbia osyridea Plant Extracts
Background: Euphorbia plants are traditionally used in folk medicine for infections, inflammation, and cancer. Objectives: To investigate the effects of the butanolic extracts of Euphorbia micorociadia and Euphorbia osyridea on specific transcription factors and cytokines expression of T cell subsets. Methods: Activated mouse splenocytes were cultured in the presence of non-cytotoxic concentrat...
متن کاملCD127 and CD25 expression defines CD4+ T cell subsets that are differentially depleted during HIV infection.
Decreased CD4(+) T cell counts are the best marker of disease progression during HIV infection. However, CD4(+) T cells are heterogeneous in phenotype and function, and it is unknown how preferential depletion of specific CD4(+) T cell subsets influences disease severity. CD4(+) T cells can be classified into three subsets by the expression of receptors for two T cell-tropic cytokines, IL-2 (CD...
