HSP70i and other stress proteins have been used in anti-tumor vaccines. This begs the question whether
HSP70i plays a unique role in immune activation. We vaccinated inducible HSP70i (Hsp70-1) knockout mice
and wild-type animals with optimized TRP-1, a highly immunogenic melanosomal target molecule. We were
unable to induce robust and lasting depigmentation in the Hsp70-1 knockout mice, and in vivo cytolytic
assays revealed a lack of cytotoxic T-lymphocyte activity. Absence of T-cell...
