Feeding channel created by malaria parasite - a new target for malaria treatments

Researchers have found pore-like holes in the membranes of red blood cells infected by the deadliest form of the malaria parasite. The parasite, Plasmodium falciparum, apparently uses these holes to supply itself with the nutrients it needs to grow and reproduce. The discovery may lead to the developmen...

...s is a retrovirus that binds to receptors found on membranes of immune system T cells. When HIV attacks a cell, the virus is internalized, copied into DNA, then migrates into the nucleus where it inserts itself as part of the host DNA. In many cases, the inserted viral genes remain dormant, sometimes for as lo...
