Cancer immunotherapy can use small numbers of ‘stem-like’ immune cells to destroy large tumors in mice

A new approach to stimulating immune cells enhances their anticancer activity, resulting in a powerful anti-tumor response in mice, according to a study by researchers at the National Cancer Institute, a part of the National Institutes of Health. This work represents an important advance in the development of immunotherapy for cancer and appears online June 14, 2009 in Nature Medicine.

Mouse experiments shed light on age effects in arthritis

Older mice are more susceptible to proteoglycan-induced arthritis (PGIA). Researchers writing in BioMed Central's open access journal Immunity & Ageing have shown, for the first time, that young mice are completely resistant, but become fully susceptible to the disease with age.

New drug for muscle degenerating diseases shows great promise

A new drug being studied for the treatment of muscle degenerating diseases has shown promising results. According to a study published today in the British Journal of Pharmacology, Debio 025 is as effective as current drugs but, crucially, does not cause unwanted immunosuppressive effects.

New discovery about mycobacteria – implications for tuberculosis research

A close relative of the microorganism that causes tuberculosis in humans has been found to form spores. This is a sensational finding because researchers have long been convinced that these kinds of bacteria - the mycobacteria - were incapable of forming spores.

Drug-resistant tuberculosis a very real threat in the Pacific region

Health officials in the Pacific are concerned about two new strains of tuberculosis - multi drug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) - both strains have been found to be resistant to the two most powerful drugs that have been used to treat tuberculosis (TB) for the past five decades.

Cigarette smoking does not affect everyone in same way

Cigarette smoking induced COPD, or chronic obstructive pulmonary disease, is a disease that results in severe breathing difficulty. According to World Health Organization (WHO) it is the fourth leading killer worldwide. However the mechanisms responsible for some smokers developing COPD and others evading the disease have not been well understood.

Cancer vaccine efficacy enhanced using anti-diabetic drug Metformin

After a vaccination or an infection, the human immune system remembers to keep protecting against invaders it has already encountered, with the aid of specialized B-cells and T-cells. Immunological memory has long been the subject of intense study, but the underlying cellular mechanisms regulating the generation and persistence of long-lived memory T cells remain largely undefined. Now, University of Pennsylvania School of Medicine researchers have found that a common anti-diabetic drug might enhance the effectiveness of vaccines. The findings are described this week in an advanced online publication of Nature.
