  • Heat shock proteins (HSPs) are intracellular molecular chaperones that play essential roles in facilitating protein folding
  • their ability to interact with APCs and to chaperone antigenic peptides for cross-presentation to MHC class I and class II molecules on APC
  • vaccination with HSP70 was associated with increased T cell, as well as NK cell, activity in patients with CML
  • ...6 more annotations...
  • HSP70 did not activate NK cells directly. Instead, HSP70 induced the expression of an NKG2D ligand MICA on DCs, which then activated NK cells in an NKG2D-dependent manner.
  • DCs are the most powerful professional antigen presenting cells (APCs) that are instrumental in processing antigens and orchestrating antigen-specific adaptive immunity and tolerance
  • NK cells and DCs can functionally interact with each other both in vitro and in vivo
  • autologous HSP70 could stimulate significant IFN-γ production
  • The magnitude of the IFN-γ response was different from patient to patient and correlated with the number of functional NK cells
  • In addition, 10 out of 14 patients had significantly increased IFN-γ producing cells in the peripheral blood after HSP70 vaccinations, which is again in line with increased NK cell activity as reported in our original study in these patients
