Characterization of an I-E-restricted, gp63-specific, CD4-T-cell clone from Leishmania major-resistant C3H mice that secretes type 2 cytokines and exacerbates infection with L. major.

A T-cell clone (designated KLmB-3) was derived from resistant C3H mice 2 weeks after infection with Leishmania major. KLmB-3 was a CD4-T-cell clone that utilized the V beta 8.1 T-cell receptor.
