Potential role in HIV treatment and prevention under study Scientists have identified a new HIV-suppressing protein in the blood of people infected with the virus. In laboratory studies, the protein, called CXCL4 or PF-4, binds to HIV such that it cannot attach to or enter a human cell. The research was led by Paolo Lusso, M.D., Ph.D., chief of the Section of Viral Pathogenesis in the Laboratory of Immunoregulation at the National Institute of Allergy and Infectious Diseases (NIAID), part...

A previously unknown serine protease forms part of the antibacterial defense arsenal of neutrophil granulocytes Neutrophil granulocytes comprise important defenses for the immune system. When pathogenic bacteria penetrate the body, they are the first on the scene to mobilize other immune cells via signal molecules, thereby containing the risk. To this end, they release serine proteases — enzymes that cut up other proteins to activate signal molecules. Scientists at the Max Planck...

4 signaling substances control the transformation of T cells The thymus plays a key role in the body's immune response. It is here where the T lymphocytes or T cells, a major type of immune defense cells, mature. Different types of T cells, designated to perform specific tasks, arise from progenitor cells that migrate to the thymus from the bone marrow. Researchers at the Max Planck Institute of Immunology and Epigenetics in Freiburg have generated artificial thymus tissue in a mouse...

(Ivanhoe Newswire) — Give it time, time heals all wounds, these words of wisdom are true when it comes to healing. As healing progresses, the need to grow new blood vessels is critical to providing nutrients and oxygen; however, it takes time to grow these necessary blood vessels. Wound healing requires complex interactions between cells resident at the damaged site and infiltrating immune cells. Endothelial progenitor cells (EPCs) are cells that come from the bone marrow and are...

Wound healing requires complex interactions between cells resident at the damaged site and infiltrating immune cells. As healing progresses, the growth of new blood vessels is critical to provide nutrients and oxygen. Endothelial progenitor cells (EPCs) are cells that come from the bone marrow and are key to the production of new vessels, but the signals that direct their emigration from the bone marrow are unknown. In this paper, Toshikazu Kondo and colleagues at Wakayama Medical University,...
