Lol p 5-derivatives with reduced allergenicity and conserved T-cell reactivity
摘要
Variants (A) of group 5 allergens of the Pooideae that have, relative to the wild-type allergen (B), reduced immunoglobulin E reactivity but essentially unchanged reactivity with T lymphocytes. Independent claims are also included for the following: (1) DNA (I) that encodes (A); (2) recombinant expression vector (EV) that contains (I) and functionally linked expression control sequences; (3) host organisms transformed with (I) or EV; and (4) preparation of (A) by culturing the organisms of (3). ACTIVITY : Antiallergic. No details of tests for antiallergic activity are given. MECHANISM OF ACTION : Immunotherapy (hyposensitization); Vaccine.
