Generation of an antibody that recognizes Plasmodium chabaudi cysteine protease (chabaupain-1) in both sexual and asexual parasite life cycle and evaluation of chabaupain-1 vaccine potential

Malaria cysteine proteases have been shown to be immunogenic and are being exploited as serodiagnostic markers, drug and vaccine targets. Several Plasmodium spp. cysteine proteases have been described and the best characterized of these are the falcipains, a family of papain-family enzymes. Falcipain-2 and falcipain-3 act in concert with other proteases to hydrolyze host erythrocyte hemoglobin in the parasite food vacuole.

Inhibitors of bacterial efflux pumps that also inhibit efflux pumps of cancer cells.

  • Authors: Amaral L, Armada A, Handzlik J, Kiec-Kononowicz K, Martins A, Molnar J, Spengler G
  • Journal: Anticancer Research
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/22753759

Bacteria and cancer cells frequently increase their resistance to chemotherapeutics as a consequence of therapy. Whenever studied, refractory response to chemotherapy is due to the over-expression of efflux pumps that render the bacterium or cancer cell resistant not only to the agent used for therapy, but to many, if not all other agents as well.
