Insect research yields insights for muscle control and nerve disorders in mammals

Working with fruit flies, Johns Hopkins scientists have decoded the activity of protein signals that let certain nerve cells know when and where to branch so that they reach and connect to their correct muscle targets. The proteins' mammalian counterparts are known to have signaling roles in immunity, nervous system and heart development, and tumor progression, suggesting broad implications for human disease research.

Insights into tissue-based T cells

US researchers have, for the first time, characterized T cells located in human tissues, rather than in the blood.

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.

Molecule imitating a virus may trigger inappropriate immune response

Why would our immune system turn against our own cells? This is the question that the combined Inserm/CNRS/ Pierre and Marie Curie University/Association Institut de Myologie have strived to answer in their "Therapies for diseases of striated muscle", concentrating in particular on the auto-immune disease known as myasthenia gravis.

House passes bio-threat vaccines, Medicare coverage bills

The House passed several health measures Wednesday including bills on developing vaccines to thwart bio-threats and on Medicare coverage for immune deficiency care.

Researchers create first ever atlas of immune cells in the human body

By analyzing tissues harvested from organ donors, Columbia University Medical Center (CUMC) researchers have created the first ever "atlas" of immune cells in the human body.

Study finds new signaling pathway involved in development of chronic inflammation of brain cells

The number of Alzheimer's patients will continue to dramatically increase in the next several decades. Various teams of researchers worldwide are feverishly investigating precisely how the illness develops. A

Australian scientists receive grants for research on cancer, malaria and rheumatoid arthritis

Scientists at the Walter and Eliza Hall Institute in Melbourne, Australia, have received more than $16 million in Australian Government funding to pursue research into cancer, malaria, rheumatoid arthritis and the immune system, it was announced today.

Georgia State researcher discover new process to make one-time flu vaccine

A new process to make a one-time, universal influenza vaccine has been discovered by a researcher at Georgia State University's Center for Inflammation, Immunity and Infection and his partners.

Tumor cells manipulate unfolded protein response

Researchers at the University of California, San Diego School of Medicine report that tumor cells use stress signals to subvert responding immune cells, exploiting them to actually boost conditions beneficial to cancer growth.

Link between silent stroke and Parkinson's disease

Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson's disease.

Injecting LECT2 may protect against bacterial sepsis

Failure to launch an adequate immune response may be at the root of septic shock, according to a study published in The Journal of Experimental Medicine on December 17th.

New research reveals music's health benefits

Music has been incorporated into medical practice since before the ancient Greeks. However, though practitioners have been convinced of music's health benefits for thousands of years, there had been little peer-reviewed research to back them up. But recent studies are providing an empirical backbone for the anecdotal evidence.

Researchers discover two-faced group of cells at work in human colon cancer

Northwestern Medicine researchers have discovered a "two-faced" group of cells at work in human colon cancer, with opposing functions that can suppress or promote tumor growth. These cells are a subset of T-regulatory (Treg) cells, known to suppress immune responses in healthy individuals.

Arginase, IDO could hold clues to help 79 million Americans with prediabetes

Two enzymes that are elevated in prediabetes could hold clues to helping the 79 million Americans with the condition avoid serious vascular complications and maybe even identify those most at risk for full-blown diabetes, researchers say.

Patients with multiple sclerosis have low levels of Egr2/3 protein in T lymphocytes

Researchers from Queen Mary, University of London have discovered that two proteins which are believed to play a key role in controlling the body's immune response are found in lower levels in T lymphocytes from patients with multiple sclerosis (MS).

AstraZeneca, Case Western Reserve initiate AZD5847 Phase 2a trial in TB

Case Western Reserve University School of Medicine and AstraZeneca, a global biopharmaceutical company, today announced the first patient enrolled in a Phase 2a trial to assess the effectiveness of AZD5847, a new test drug for patients with tuberculosis (TB), including patients with HIV co-infection.

Blocking myeloid-derived suppressor cells after lymphopenia improves adoptive T-cell therapy

Researchers at the Moffitt Cancer Center have found that delayed tumor growth and enhanced survival of mice bearing melanoma were possible by blocking the reconstitution of myeloid-derived suppressor cells and Tregs (suppressors of anti-tumor activity) after total body irradiation had eliminated them. Blocking myeloid-derived suppressor cells and regulatory T-cell reconstitution improved adoptive T-cell therapy, an immunotherapy designed to suppress tumor activity.

Study finds high serum galectin-1 levels in Hodgkin lymphoma patients

Blood levels of an immunity-related protein, galectin-1, in patients with newly diagnosed Hodgkin lymphoma reflected the extent of their cancer and correlated with other predictors of outcome, scientists reported at the American Society of Hematology annual meeting.

Severe RSV disease may impair innate immune response in infants

Infants with severe lower respiratory tract infection caused by respiratory syncytial virus (RSV) may have a dysfunctional innate immune response that relates to the severity of their disease.
