Demonstration of the stability of the membrane phenotype of T helper cells after priming and boosting with a hapten‐carrier conjugate

Abstract

Evidence is presented that the phenotype of the rat T helper cells is stable after priming and boosting with a hapten-carrier conjugate and that the phenotype is W3/25⁺, MRC OX-22⁻, MRC OX-8⁻. Data are also presented that demonstrate the presence of doubly marked, W3/25⁺, MRC OX-8⁺, cells in the spleens of rats primed 1 week previously.
