15-01-29 Antioxidants are natural food ingredients that protect cells from harmful influences. Their main task is to neutralize so-called free radicals which are produced in the process of oxidation and which are responsible for cell degeneration. Scientists...

15-01-20 A group of white blood cells known as B cells, which play a key role in the human immune response, need a protein-targeting signal called mannose 6-phosphate (M6P) in order to proliferate, differentiate, and present immune cell-activating antigens,...

14-12-17 Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system -- the first line of defense against disease-causing microbes. In a new study, Yixin Shi, Ph.D., and Wei Kong, Ph.D., re...

14-11-27 Mouse cells and tissues created through nuclear transfer can be rejected by the body because of a previously unknown immune response to the cell's mitochondria, according to a study in mice by researchers at the Stanford University School of Medicin...

14-06-11 Scientists believe they have an explanation for the axiom that stress, emotional shock, or overexertion may trigger heart attacks in vulnerable people. Hormones released during these events appear to cause bacterial biofilms on arterial（动脉的） wa...

14-06-04 New research on innovative immunotherapies for advanced or high-risk melanoma（黑素瘤） and cervical（子宫颈的） cancer were presented today at the 50th Annual Meeting of the American Society of Clinical Oncology (ASCO). These treatments -- used alo...

14-04-19 The cause of neuronal death in Parkinson's disease is still unknown, but a new study proposes that neurons may be mistaken for foreign invaders and killed by the person's own immune system, similar to the way autoimmune diseases like type I diabetes...

14-04-17 A research team at the Biozentrum of the University of Basel has discovered an protein family that plays a central role in the fight against the bacterial pathogen Salmonella within the cells. The so called interferon-induced GTPases reveal and elim...

14-01-09 An international team of researchers has sequenced the genome of the elephant shark, a curious-looking fish with a snout（鼻子） that resembles the end of an elephant's trunk. The elephant shark and its cousins the sharks, rays, skates and chimaeras...

13-12-13 Bacteria can evolve rapidly to adapt to environmental change. When the environment is the immune response of an infected host, this evolution can turn harmless bacteria into life-threatening pathogens. A study published on December 12 in PLOS Pathog...
