B and T lymphocyte attenuator (BTLA) is a co-inhibitory receptor that is expressed by lymphoid cells and regulates the immune response.

We recently demonstrated that the BTLA pathway is altered in CD4+ T cells from lupus patients. https://www.chiggate.com/eeboo-memory-matching-game-animal-pre-school-supply/
