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.

Researchers identify 25 human proteins that may be crucial for HIV-1 infection and survival

Studying HIV-1, the most common and infectious HIV subtype, Johns Hopkins scientists have identified 25 human proteins "stolen" by the virus that may be critical to its ability to infect new cells. HIV-1 viruses capture many human proteins from the cells they infect but the researchers believe these 25 proteins may be particularly important because they are found in HIV-1 viruses coming from two very different types of infected cells.

Researchers map complex interactions of proteins that control inflammation

Inflammatory response plays a major role in both health protection and disease generation. While the symptoms of disease-related inflammatory response have been know, scientists have not understood the mechanisms that underlie it.

Boston College biologist receives $2.7M NIH grant to continue HIV and AIDS research

Boston College biologist Ken Williams, whose research focuses on the role of immunological cells in a range of illnesses that strike people living with HIV and AIDS, has been awarded a five-year, $2.7 million grant from the NIH's National Institute of Neurological Disorders and Stroke.

Researchers discover miR-27b that regulates lipid levels in the blood

Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia-abnormal blood cholesterol levels that can contribute to heart disease.

Oral eosinophilic ulcers ‘a self-limiting, reactive condition’

A review of patients with oral eosinophilic ulcers suggests that the lesions should be considered a reactive, local condition rather than a CD30+ lymphoproliferative disorder.

Liver gene found to regulate cholesterol and fat blood levels

Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia—abnormal blood cholesterol levels that can contribute to heart disease.

Glimmer of hope for imatinib-resistant GIST

The monoclonal antibody SR1 can significantly inhibit gastrointestinal stromal tumor cell growth, report researchers in the Proceedings of the National Academy of Sciences.

Boston College biologist to explore connection between peripheral neuropathy and HIV

Boston College biologist Tricia Burdo has been awarded a five-year, $1.9 million grant from the National Institutes of Health to study the role of the body's immune response in a debilitating form of nerve damage suffered by people living with HIV.

Researchers pinpoint how vitamin D3 and omega-3 may boost immunity to help fight Alzheimer's

A team of academic researchers has pinpointed how vitamin D3 and omega-3 fatty acids may enhance the immune system's ability to clear the brain of amyloid plaques, one of the hallmarks of Alzheimer's disease.

Cloaked nanoparticles escape immune system surveillance to reach desired target

By cloaking nanoparticles in the membranes of white blood cells, scientists at The Methodist Hospital Research Institute may have found a way to prevent the body from recognizing and destroying them before they deliver their drug payloads. The group describes its "LeukoLike Vectors", or LLVs, in the January issue of Nature Nanotechnology.

Study shows how placental circulation can influence malarial parasite behavior and infection

Malaria in pregnancy causes a range of adverse effects, including abortions, stillbirths, premature delivery and low infant birth weight. Many of these effects are thought to derive from a placental inflammatory response resulting from interaction of infected red blood cells with the placental tissue.

Mount Sinai to initiate immunological therapy trial against chronic pulmonary sarcoidosis

Patients are currently being enrolled in the first clinical trial to investigate the efficacy of immunological therapy for chronic pulmonary sarcoidosis. The trial is being conducted by researchers at the Icahn School of Medicine at Mount Sinai.

Normalizing p62 protein levels in immune system cells could reduce infection in CF patients

New research suggests that lowering excessive levels of a protein in immune system cells could be a strategy to clear an infection that is deadly to patients with cystic fibrosis (CF).

Neonatal chemokines altered in autistic spectrum patients

A study by scientists has found limited evidence to support a role for proinflammatory chemokines in the pathophysiology of Autism Spectrum Disorders.

Uncharacterized TLR plays key role in Toxoplasma gondii response

A previously uncharacterized toll-like receptor appears to play a crucial role in the innate immune response to Toxoplasma gondii infection and may promote host resistance, potentially leading to anti-parasite vaccines, say US researchers.

Scientists identify molecular mechanism central to development of osteoarthritis pain

Researchers at Rush University Medical Center, in collaboration with researchers at Northwestern University, have identified a molecular mechanism central to the development of osteoarthritis (OA) pain, a finding that could have major implications for future treatment of this often-debilitating condition.

Immune-promoting drugs may control recurrent disease

Nearly half of the 700,000 cancer patients who undergo surgical removal of a primary tumor each year suffer a recurrence of their disease at some point, and many of those patients will eventually die from their disease.
