NEW MECHANISMS OF NK CELLS ACTIVATION DURING VIRAL INFECTIONS

Natural killer (NK) cells are cytotoxic lymphocytes which constitute a significant element of innate immune responses against tumours and cells infected with viruses or parasites. The function of NK cells is tightly regulated and depends on the balance between activating and inhibitory signals. This review focuses on the latest research showing a high redundancy of mechanisms regulating the activity of NK cells during viral infections and indicating their involvement in the adaptive immune response.

APOPTOSIS MARKERS IN BLOOD PLATELETS

Blood platelets, enucleate cells derived from megakaryocytes, play an essential role in haemo- stasis and thrombosis. They may be involved probably in platelet activation and programmed death. The experimental evidences discussed in this review indicate that during aging and activation platelets express apoptotic markers similar to those found in nucleated cells.
