A New Research Demonstrates HIV-1 In Resident Immune Cells Of Human Testis

...finding that HIV-1 can replicate within testicular macrophages is significant because the testis represents a pharmacological sanctuary—many anti-retroviral drugs have difficulty penetrating this organ and may be present at sub-therapeutic levels. Thus, although HAART may achieve undetectable virus levels in the...

Clues Found On How Deadly Bacterium Gains Foothold

...a could live inside other white blood cells called macrophages and not be killed by them," Allen said. "But little research had been done on the bacteria's survival in neutrophils. "Early data indicated that neutrophils did not kill Francisella well. With new techniques, many of them more sensitive than in yea...

Vitamin D3 Protects Skin from Harmful Microbes

...n. Researchers focused on white blood cells called macrophages that work to destroy invading bacterial microbes. Macrophages contain toll-like receptors that identify the invaders; when the receptors sense the presence of bacteria, they trigger cathelicidin production. Gallo’s team has now discovered that in...

Cells in the Lung Clear the Air to Prevent Lung Damage

...more of a protein known as MARCO than the alveolar macrophages of mice susceptible to ozone-induced lung damage. ...CO. MARCO provided protection by enabling alveolar macrophages to take up lipids in the lung modified by the oxidant that would initiate an inflammatory reaction i...

CT Imaging With Novel Contrast Agent May Predict Heart Attack in Waiting

IDRI and Chembio to Develop Tests for Leishmaniasis and Leprosy

...s. Leishmania are protozoan parasites that inhabit macrophages or the white blood cells of the immune system. The parasites are transmitted by the bite of small blood sucking insects (sand flies), which are difficult to control, as they inhabit vast areas of the planet. It is estimated that about 500,000 new cas...

Macrophages may Help Prevent Obesity

... on a study that highlights the beneficial role of macrophages in combating the effects of a high fat diet in mic.... It was found that simply missing PPAR-gamma in macrophages caused mice to gain about 20 per cent more weight than their normal counterparts, and predisposed th...

Cigarette Smoking Delays Ligament Healing

...everal days of inflammation, in which cells called macrophages flock to the injury site and secrete substances called cytokines and chemokines. Those, in turn, recruit more cells to assist in healing. That process of cellular proliferation and synthesis lasts for several days to several weeks. The final stage ...

Curry Ingredient Kills Plaque Leading to Alzheimer's

...t bisdemethoxycurcumin boosted immune cells called macrophages to clear amyloid beta. In addition, researchers identified the immune genes associated with this activity.The study is important as it provides more insight into the role of the immune system in Alzheimers disease and points to a new treatment appr...
