Vitamin D May Help In Fight Against Tuberculosis

...however poorly understood in human beings. Human macrophages have a set of receptors (toll like receptors) that contribute to innate immunity. It ahs now been shown that this may be to a large extent dependent on absorption, storage and utilization of Vitamin D. Stimulation of toll like receptors by specific m...

Study Would Pave Way for the Development of New Drugs That Targets TB Proteasome

... kept in check within immune system cells known as macrophages by compounds such as nitric oxide that kills or disables most of the bacteria. Inside the macrophage the immune cells damages and destroys the bacterial proteins. These accumulated proteins have to be removed otherwise it will in turn destroy the cel...

Tumor Resistant Mice Point To Novel Cancer Treatments

...led cytolysis. A combination of WBCs (neutrophils, macrophages and natural killer cells) from the special mice was then injected into mice with tumors. As expected, these injected cells were found to destroy the tumor, even the most aggressive forms. More importantly the healthy tissue was unaffected and norma...

Nanotechnology Could Revolutionize Cardiac Treatment

...e opposite effect,’ he said. Mogue explains that macrophages accumulate large amounts of oxidized LDL and secrete chemicals that can damage the neighboring tissues and, ultimately, become fatty foam cells. The researchers' approach, therefore, is to create clusters of nanoengineered molecules that target speci...

'Oncomodulin'- Path To Nerve Regeneration

...an inflammatory reaction occurred which stimulated macrophages which are immune cells to move into the axons and release an unidentified protein which causes nerve regeneration. But for oncomdulin to work it requires an agent which should increase cyclic AMP which initiates various cellular reactions and helps m...

Well-Planned Surgeries Also Carry Health Risks

...st.” The mice die rapidly and these re-programmed macrophages may help explain why children with sickle cell disease are more prone to overwhelming and potentially deadly infections following surgery. “We need more investigations, more data on humans,” says Dr. Meiler, noting that while short-term outcomes of ...

Cancer Drug Helps An Anti-Cancer Virus To Act More Exhaustively

...he virus, she found that high numbers of NK cells, macrophages and brain-tissue immune cells called microglia had moved into the tumour. The number of macrophages, for example, had raised three fold. In animals given the drug, on the other hand, the number of these immune cells increased by only one half. Othe...
