A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Cholesterol efflux capacity is more closely associated with protection against heart disease: Study

The discovery that high levels of high-density lipoprotein cholesterol is associated with reduced risk of cardiovascular disease has fostered intensive research to modify HDL levels for therapeutic gain. However, recent findings have called into question the notion that pharmacologic increases in HDL cholesterol levels are necessarily beneficial to patients.

Omega-3 fatty acid may help protect against traumatic brain injury

Animal experiments suggest that taking the omega-3 fatty acid docosahexanoic acid (DHA) might offer a new way of protecting against traumatic brain injury (TBI), reports the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

HRG protein inhibits tumor growth and metastasis: Study

Most cancer tissues are invaded by inflammatory cells that either stimulate or inhibit the growth of the tumor, depending on what immune cells are involved. Now a Swedish-Belgian research team has shown that a protein that naturally occurs in the body, HRG, inhibits tumor growth and metastasis into secondary organs by activating specific immune cells.

P. gingivalis infection accelerates inflammation and atherosclerosis in the innominate artery

Atherosclerosis is the leading cause of death in the developed world. While a number of risk factors for atherosclerosis have been defined, scientists continue to study other possible risk factors for this disease. Recent epidemiological and experimental studies link infectious agents with the development of inflammatory atherosclerosis. A hallmark of chronic infection with the oral pathogen Porphyromonas gingivalis is the induction of a chronic inflammatory response.

Certain drugs may block tumor host interactions but do not destroy cancer cells

A class of drugs thought to kill cancer cells may in fact block "cross talk" between the cancer cell and normal immune cells, resulting in reduced cancer growth and spread-a discovery that could significantly alter the way cancer drugs are evaluated in the future.

Researchers present definitive explanation of how fibrotic cells destroy human liver

In the latest of a series of related papers, researchers at the University of California, San Diego School of Medicine, with colleagues in Austria and elsewhere, present a new and more definitive explanation of how fibrotic cells form, multiply and eventually destroy the human liver, resulting in cirrhosis. In doing so, the findings upend the standing of a long-presumed marker for multiple fibrotic diseases and reveal the existence of a previously unknown kind of inflammatory white blood cell.

Study shows breast inflammation promotes development and progression of cancer

It took 12 years and a creation of a highly sophisticated transgenic mouse, but researchers at Kimmel Cancer Center at Jefferson have finally proven a long suspected theory: Inflammation in the breast is key to the development and progression of breast cancer.

Preliminary results from Phase 1b/2a trial of MediciNova's ibudilast in opioid addicts announced

Drug addiction investigators with joint appointments at Columbia University Medical Center and the New York State Psychiatric Institute along with MediciNova Inc, a biopharmaceutical company publicly traded on the Nasdaq Global Market and the Jasdaq Market of the Osaka Securities Exchange, today reported preliminary results of the company's neurological drug candidate, ibudilast (MN-166/AV411), in a Phase 1b/2a trial in opioid addicts. The study was largely funded by the National Institute on Drug Abuse (NIDA) with MediciNova supplementation.

Scientists discover key molecular events in immune system that contribute to inflammatory bowel disease

Scientists at the Virginia Bioinformatics Institute at Virginia Tech have discovered some of the key molecular events in the immune system that contribute to inflammatory bowel disease.

Researchers target MIC-1 protein to halt growth of melanoma tumors

Halting the growth of melanoma tumors by targeting the MIC-1 protein that promotes blood vessel development in tumors may lead to better treatment of this invasive and deadly cancer, according to Penn State College of Medicine researchers in The Foreman Foundation Research Laboratory.

Some key molecular events in immune system contribute to inflammatory bowel disease: Scientists

Scientists at the Virginia Bioinformatics Institute at Virginia Tech have discovered some of the key molecular events in the immune system that contribute to inflammatory bowel disease. The results, which help researchers move one step further in their efforts to develop new drugs to treat inflammatory and immune-mediated diseases, are reported in the November 2010 edition of the journal Mucosal Immunology from the Nature Publishing Group.

Appropriate level of Static Magnetic Field exposure for wound patients needs to be considered

The interest in the biological effects of non-ionizing Electro Magnetic Fields (EMFs) and Static Magnetic Fields (SMFs) on the whole organism, as well on cellular systems, has noticeably increased in recent years in consideration of their increased production (from the generation and transmission of electricity, to domestic appliances and industrial equipment, to telecommunications and broadcasting) and the possible health risk for humans.

Trillium presents results from cancer stem cell program at ASH Annual Meeting

Trillium Therapeutics Inc. (TTI), a biopharmaceutical company developing innovative immune-based biologics, today announced that preliminary results from its cancer stem cell program, targeting the CD47 protein, will be reported in an oral presentation at the 52nd American Society of Hematology (ASH) Annual Meeting to be held in Orlando, Florida, December 4-7, 2010.

Lipids react and change to bacterial stimulus, trigger cell's immune response

For the first time, scientists have described not only the identities and quantities of fat species in a living mammalian cell in this case, a mouse macrophage or white blood cell but they also report how these lipids react and change over time to a bacterial stimulus triggering the cell's immune response.

Angptl4 protein deficiency could promote inflammatory response in people who consume high saturated fat

A new report in the December Cell Metabolism identifies a protein without which diets high in saturated fat lead to a massive inflammatory response that can prove fatal. The studies in mice suggest that deficiencies in this protective pathway could promote inflammation in those who regularly consume high levels of saturated fat.
