- Description
- Description: The 14D3 monoclonal antibody reacts with human CD152, also known as cytotoxic T lymphocyte antigen-4 (CTLA-4). CTLA-4, a protein with structural similarities to CD28, is expressed on activated T cells (activated B cells may also express CTLA-4) and binds the B7 family members, CD80 (B7-1) and CD86 (B7-2), with higher affinity than CD28 does. CTLA-4 and CD28 appear to deliver opposing signals to T cells: while CD28 is a potent costimulator, CTLA-4 restricts the progression of T cells to an activated state by inhibiting IL-2 secretion and cellular proliferation. The cytoplasmic portion of CTLA-4 contains ER retention motifs, resulting in intracellular localization of a large proportion of newly synthesized CTLA-4 in response to TCR signaling.

- Figure 2 T FR expansion in lymphoid tissues during chronic SIV infection. ( a ) Disaggregated lymph node and spleen cells from SIV uninfected ( n =9) or chronically SIV-infected rhesus macaques ( n =11) were analysed by flow cytometry. Representative examples of flow cytometry gating are shown. Of viable CD3 + CD8 - cells, follicular subsets were defined as CXCR5 + cells (F) and germinal centre subsets were defined as CXCR5 hi PD-1 hi cells (GC). Of these subsets, regulatory cells were defined as CD25 hi CD127 - . T FR (CXCR5 + CD25 hi CD127 - ) were Foxp3 + , whereas T FH (CXCR5 + CD25 lo/- ) were Foxp3 - . ( b ) The percentages of each rhesus macaque regulatory subset, as analysed in a are shown. ( c ) The ratios of each regulatory cell population to its non-regulatory cell counterpart are shown.
