... • Helper T-cells: present the pathogen’s antigen to B-cells and cytotoxic T-cells • B-cells: makes antibodies directed toward a specific antigen; target the antigen for removal • Cytotoxic T-cells: make proteins called receptors specific to the one antigen; sticks to antigen and kills it • Suppress ...

Autoimmune Diseases
... •Regulatory T cells play a crucial in controlling autoimmune responses: CD25+FoxP3+ CD4+T cells block the effect of autoimmune responses mediated by autoreactive T cells. This blocking may or may not require the secretion of suppressive cytokines such as TGF and IL-10. Some autoimmune diseases appe ...

Auto-immune diseases – 19/03/03

Immunologic tolerance, therefore, can be induced either when lymphocytes are maturing in lymphoid organs called central tolerance, or when they are matured and come into contact with self antigens called peripheral tolerance. Periphe ...
