Malarial pigment enhances heat shock protein–27 in THP–1 cells: new perspectives for in vitro studies on monocyte apoptosis prevention

Conclusions Present data show that HZ prevents cell apoptosis and enhances the expression of anti-apoptotic HSP-27 in THP-1 cells, confirming the previous evidences obtained from HZ-fed immunopurified monocytes. Since the use of a stable cell line is pivotal to perform HSP-27 silencing experiments, monocytic THP-1 cells could be a good candidate line for such an approach, which is heavily required to clarify the role of HSP-27 in survival of impaired HZ-fed monocytes during falciparum malaria.
