I wonder though, whether hsp70 ( the inducible isoform) may also have a
similar role to hsc70, as its sequence is very similar. It seems logical
that the immune system should be linked in some way with heat stress,
considering fever may affect both these things. Perhaps he hsp70 protein
is induced in fever to alter the way antigenic peptides are processed or
expressed.
