HIV selectively suppresses anti-HIV defense cells
... CD4+ T cells are especially vulnerable to HIV, an ideal vaccine should also create a broad and powerful CD8+ T cell response and antibodies against HIV, Douek explains. HIV does not infect CD8+ T cells, also known as cytotoxic or killer cells. A robust CD8+ response should be an important part of an HIV v...First live studies of important cell structures may shed light on Alzheimer's, other diseases
... model systems. Dictyostelium is, in many ways, an ideal though offbeat candidate for study of Hirano bodies. It has long been a model system for studies of cell structure and movement. Fechheimer found that the slime mold could be induced to form Hirano bodies in the presence of altered forms of an actin ...Virginia Tech study documents hypertension association with obesity and heavy alcohol consumption

"African-American women are at a greater risk for both obesity and hypertension," she said. "Our research shows t...Tropical scientists find fewer species than expected
... New Guinea's species diversity made the island an ideal laboratory for the study. Its tropical forests are about the same area as Texas but contain five percent of the world's biodiversity, Weiblen said. The island has 12,000 species of plants; in comparison, Weiblen's home state of Minnesota has only abo...Eliminating battlefield transfusions

...gnal of organic matter of living systems, it is an ideal technique for studies of ancient microscopic fossils. Raman imagery can show a one-to-one correlation between cell shape and chemistry, and prove whether fossils are biological. Schopf and his colleagues applied the new technique to ancient fossil mi...URI Graduate School of Oceanography scientists examine the success of restored salt marshes
...for larger fish and crustaceans, mummichogs are an ideal species to use to quantify responses to restoration. The scientific team conducted its study at Sachuest Point salt marsh in Middletown, Rhode Island. Two-thirds of the salt marsh had been tidally restricted by a road and causeway constructed across...Immerge biotherapeutics identifies miniature swine that do not transmit pig retrovirus to humans
