Hapten-specific T cell lines mediating delayed hypersensitivity to contact-sensitizing agents
Continuous cultures of T cells from the lymph nodes of mice sensitized to the contact sensitizers 4-ethoxymethylene-2-phenyl oxazolone or picryl chloride have been established. For continuous proliferation, the lines required specific antigen, syngeneic antigen-presenting cells, and growth factors from the supernatant of concanavalin-A-stimulated lymphoid cultures. Cells from the lines showed a...
متن کاملDelayed Hypersensitivity to Hapten-protein Conjugates
Further data have been presented showing that the specificity of the delayed hypersensitivity reaction in the guinea pig to hapten-protein conjugates involves to a considerable degree a contribution by the protein carrier. The carrier contribution is such that sensitization to guinea pig albumin-m-azobenzenesulfonate, for example, does not result in cross-reaction with conjugates of the same ha...
متن کاملHapten-Induced Contact Hypersensitivity, Autoimmune Reactions, and Tumor Regression: Plausibility of Mediating Antitumor Immunity
Haptens are small molecule irritants that bind to proteins and elicit an immune response. Haptens have been commonly used to study allergic contact dermatitis (ACD) using animal contact hypersensitivity (CHS) models. However, extensive research into contact hypersensitivity has offered a confusing and intriguing mechanism of allergic reactions occurring in the skin. The abilities of haptens to ...

Hapten-specific T-cell responses to 4-hydroxy-3-nitrophenyl acetyl. I. Genetic control of delayed-type hypersensitivity by VH and I-A-region genes
The primary anti-(4-hydroxy-3-nitrophenyl)acetyl (NP) antibody response is known to have a heteroclitic fine specificity, i.e., anti-NP antibodies bind (4-hydroxy-5-iodo-3-nitrophenyl)acetyl (NIP) with greater affinity than NP itself. Past studies of NP-specific DTH responses and NP-specific T cell-mediated suppression have demonstrated sharing of fine specificity patterns and idiotypic structu...
