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.

Safe to smoke?

Some Australian scientists have found that there is a new agent that can protect the lungs of mice from the harmful effects of cigarette smoke.

Blocking GM-CSF could reduce inflammation and deleterious effects of cigarette smoke exposure

Researchers in Australia have demonstrated that blocking a certain protein can reduce or prevent cigarette smoke-induced lung inflammation in mice. Inflammation underlies the disease process of chronic obstructive pulmonary disease (COPD) and many other smoking-related ailments.

New findings promise to have fundamental significance in the fight against cancer

Cells have two different protection programs to safeguard them from getting out of control under stress and from dividing without stopping and developing cancer. Until now, researchers assumed that these protective systems were prompted separately from each other.

MIF exhibits potential as viable therapeutic target for Type 2 diabetes

An experimental oral drug has lowered blood sugar levels and inflammation in mice with Type 2 diabetes, suggesting that the medication could someday be added to the arsenal of drugs used by millions of Americans with this disease, according to new research.

MPP cell population: A new potential target for treating infections and allergies

Millions of people in both the developing and developed world may benefit from new immune-system research findings from the University of Pennsylvania School of Veterinary Medicine.

Scientists identify the role of vitamin D in activation of T cells

Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system - T cells - will not be able to react to and fight off serious infections in the body.

TLR's role in HIV-1 reactivation induced by periodontal pathogens

Today, during the 39th Annual Meeting of the American Association for Dental Research, convening at the Walter E. Washington Convention Center in Washington, DC, lead researcher O.A. Gonzalez (University of Kentucky, Lexington) will present a poster of a study titled "TLR2 and TLR9 Activation by Periodontal Pathogens induce HIV-1 Reactivation."

Severe inflammatory diseases: Blocking "death messenger" might be a promising treatment

The signaling molecule CD95L, known as "death messenger," causes an inflammatory process in injured tissue after spinal cord injuries and prevents its healing. This discovery was published by scientists of the German Cancer Research Center. In mice, the researchers found out that if they switch off CD95L, the injured spinal cord heals and the animals regain better ability to move. Therefore, substances which block the death messenger might offer a new approach in the treatment of severe inflammatory diseases.

Simvastatin impairs ability of macrophages to kill pathogens, and enhances cytokine production

Simvastatin might help us control our cholesterol, but when it comes to infection, it's an entirely different story says a new research study published in the Journal of Leukocyte Biology. In the research report, scientists from Italy show that simvastatin delivers a one-two punch to the immune system. First it impairs the ability of specialized immune cells, called macrophages, to kill pathogens. Then, it enhances production of molecules, called cytokines, which trigger and sustain inflammation.

Salmonella-infected mice help understand how symptoms of HLH develop

A new University of Colorado at Boulder study shows mice infected with the bacteria salmonella develop clinical signs consistent with a deadly and poorly understood human inflammatory disease, a finding that may lead to new therapies.

α-defensins1-3 may be potential prophylactic agents in treatment of HIV / AIDS

HIV/AIDS remains one of the world's most significant public health challenges, particularly in developing countries. The Human Immunodeficiency Virus (HIV-1), the variant responsible for the pandemic, has the ability to infect different cell types such as T cells, macrophages and dendritic cells (DC). These latter cells are crucial in the defense against infectious agents and play a major role in viral pathogenesis.

Signaling molecules may link certain actions of B cells to solid tumor growth: Study

Cancer researchers studying the immune system have identified a previously unrecognized set of targets and biomarkers to battle solid tumors.

Nitric oxide may play key role in the pathogenesis of neonatal meningitis

Current research suggests that nitric oxide may play a role in the pathogenesis of neonatal meningitis. The related report by Mittal et al, "Inhibition of inducible nitric oxide controls pathogen load and brain damage by enhancing phagocytosis of Escherichia coli K1 in neonatal meningitis," appears in the March 2010 issue of The American Journal of Pathology.

GeoVax Labs presents results of preclinical study on prototype HIV/AIDS vaccine at CROI

GeoVax Labs, Inc., an Atlanta-based, biopharmaceutical company developing vaccines for diseases caused by HIV-1 (Human Immunodeficiency Virus), today announced that it presented the results of a preclinical study on a prototype HIV/AIDS vaccine at the Conference on Retroviruses and Opportunistic Infections (CROI) in San Francisco.

Signaling protein has key role in fighting bacterial infection and inflammation in intestinal tract: Study

A signaling protein that is key in orchestrating the body's overall immune response has an important localized role in fighting bacterial infection and inflammation in the intestinal tract, according to a study by UC San Diego School of Medicine investigators, published in the journal Cell Host and Microbe.

Healthy immune response depends on TRPV2 protein

If bad bacteria lurk in your system, chances are they will bump into the immune system's protective cells whose job is gobbling germs.

TB's mechanism to evade body's immune system identified

Indiana University School of Medicine researchers have identified a mechanism used by the tuberculosis bacterium to evade the body's immune system and have identified a compound that blocks the bacterium's ability to survive in the host, which could lead to new drugs to treat tuberculosis.

Scientists discover molecular pathway to regenerate damaged kidney tissues

Scientists have discovered a molecular pathway that works through the immune system to regenerate damaged kidney tissues and may lead to new therapies for repairing injury in a number of organs.

Antibodies also contribute to severe dengue virus-induced disease, confirms La Jolla Institute for Allergy & Immunology

A leading immunology research institute has validated the long-held and controversial hypothesis that antibodies - usually the "good guys" in the body's fight against viruses - instead contribute to severe dengue virus-induced disease, the La Jolla Institute for Allergy & Immunology announced today. The finding has major implications for the development of a first-ever vaccine against dengue virus, a growing public health threat which annually infects 50 to 100 million people worldwide, causing a half million cases of the severest form.
