Mouse CD1-autoreactive T cells have diverse patterns of reactivity to CD1+ targets.
Humans and mice contain significant populations of T cells that are reactive for autologous CD1 molecules. Using a panel of five mouse CD1 (mCD1)-autoreactive T cell hybridomas, we show here that this autoreactivity does not correlate with the level of CD1 expression. In some cases, these autoreactive T cells can distinguish between different cell types that express the same CD1 molecule, sugge...
متن کاملGlycolipid targets of CD1-mediated T-cell responses.
Members of the CD1 family of antigen-presenting molecules bind and present a variety of mammalian and microbial glycolipids for specific recognition by T cells. CD1 proteins accomplish their antigen-presenting function by binding the alkyl chains of the antigens within a deep, hydrophobic groove on the membrane distal surface of CD1, making the hydrophilic elements of the antigen available for ...
متن کاملHuman CD1-restricted T cell recognition of lipids from pollens
Plant pollens are an important source of environmental antigens that stimulate allergic responses. In addition to acting as vehicles for foreign protein antigens, they contain lipids that incorporate saturated and unsaturated fatty acids, which are necessary in the reproduction of higher plants. The CD1 family of nonpolymorphic major histocompatibility complex-related molecules is highly conser...
متن کاملDrugs inducing T-cell mediated cutaneous adverse reactions and contact sensitizers evoke similar responses in THP-1 cells
Background Contact sensitizers induce an innate immune response in dendritic cells (DC) enhancing antigen presentation and T cell response. Little is known concerning the effect of systemic drugs causing T-cell mediated cutaneous adverse drug reactions (CARDs). Therefore, we studied the in vitro effect of drugs on THP-1 cells, a monocyte cell line widely used to show activation by contact sensi...
متن کاملT-cell responses to CD1-presented lipid antigens in humans with Mycobacterium tuberculosis infection.
CD1-restricted presentation of lipid or glycolipid antigens derived from Mycobacterium tuberculosis has been demonstrated by in vitro experiments using cultured T-cell lines. In the present work, the frequency of T-cell responses to natural mycobacterial lipids was analyzed in ex vivo studies of peripheral blood lymphocytes from human patients with pulmonary tuberculosis, from asymptomatic indi...
