Flu vaccine research: Overcoming ‘original sin’

Flu vaccine research: Overcoming ‘original sin’

ScienceDaily (Aug. 17, 2012) — Scientists studying flu vaccines have identified ways to overcome an obstacle called “original antigenic sin,” which can impair immune responses to new flu strains. Original antigenic sin (OAS) is a situation where the immune system is fighting with obsolete weapons and has trouble adapting. Continue reading

Combination peptide therapies might offer more effective, less toxic cancer treatment

Combination peptide therapies might offer more effective, less toxic cancer treatment

ScienceDaily (Aug. 16, 2012) — Two studies suggest that two peptide agents used either together or individually with a low-dose of a standard chemotherapy drug might offer more effective cancer therapy than current standard single-drug treatments. Continue reading

Genetic material in blood cells may affect malaria parasites

Genetic material in blood cells may affect malaria parasites

ScienceDaily (Aug. 15, 2012) — Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells. In a finding that has eluded scientists for years, Duke researchers discovered that genetic material in red blood cells may help alter parasite activity via a novel mechanism that alters parasite gene regulation.
