Distinct subsets of human invariant NKT cells differentially regulate T helper responsesvia dendritic cells

Type II NKT cells differentially regulate CD4 T cell subsets

Natural killer T (NKT) cells lie at the interface between the innate and adaptive immune systems and are important mediators of tumor immunosurveillance. This CD1d-restricted lymphoid population recognizes lipid antigen and can rapidly produce an array of cytokines and chemokines to modulate the host immune response. In tumor immunity, two NKT cell subsets (type I and type II) have contrasting ...

Human invariant NKT cell subsets differentially promote differentiation , antibody production and T cell stimulation by B cells in vitro 1

Invariant natural killer T (iNKT) cells can provide help for B cell activation and antibody production. Since B cells are also capable of cytokine production, antigen presentation and T cell activation, we hypothesized that iNKT cells will also influence these activities. Furthermore, subsets of iNKT cells based on CD4 and CD8 expression that have distinct functional activities may differential...

Human invariant NKT cell subsets differentially promote differentiation, antibody production, and T cell stimulation by B cells in vitro.

Invariant NK T (iNKT) cells can provide help for B cell activation and Ab production. Because B cells are also capable of cytokine production, Ag presentation, and T cell activation, we hypothesized that iNKT cells will also influence these activities. Furthermore, subsets of iNKT cells based on CD4 and CD8 expression that have distinct functional activities may differentially affect B cell fun...

Fibroblast and T cells conditioned media induce maturation dendritic cell and promote T helper immune response

Dendritic cells (DCs) induce pathogen-specific T cell responses. We comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), PHA activated T cells (T cell conditioned medium), and mixture of fibroblast & PHA activated T cells (FCM-TCCM) conditioned media on maturation of DCs. Monocytes were cultured with GM-CSF and IL-4 for five days. ...
