What if we could engineer a liver or kidney from a patient's own stem cells? How about helping regenerate tissue damaged by diseases such as osteoporosis and arthritis? A new UCLA study bring scientists a little closer to these possibilities by providing a better understanding how tissue is formed and organized in the body. A UCLA research team discovered that migrating cells prefer to turn right when encountering changes in their environment. The researchers were then able to translate...

In a study investigating immune response in cancer, researchers from Moffitt Cancer Center in Tampa, Fla., and the University of South Florida have found that interaction between the immune system's antigen-specific CD4 T cells and myeloid-derived suppressor cells (MDSC) - cells that play a major role in cancer-related immune suppression - dramatically change the nature of MDSC-mediated suppression. By contrast, the same effect was not observed when MDSCs interacted with the immune system's...

New research published in the Journal of Leukocyte Biology suggests that high levels of estradiol present prior to ovulation decreases immune system effectiveness resulting in growth and promotion of infection A new research report in the Journal of Leukocyte Biology (http://www.jleukbio.org) suggests that a woman's ovarian cycle plays an important role in her susceptibility to infection. Specifically, researchers from Spain and Austria found that women are most susceptible to infection,...

Vaccines with broader reach might be made by stimulating specialized immune cells to recognize foreign cell membrane proteins that are shared across bacterial species, say researchers from Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine in a report published online today in Immunity. The approach could be particularly beneficial in preventing infection by multi-drug resistant organisms. The genetic heritage of organisms such as oysters, frogs...

It is vital that the body's own immune system does not overreact. If its key players, the helper T cells, get out of control, this can lead to autoimmune diseases or allergies. An immune system overreaction against infectious agents may even directly damage organs and tissues. Immune cells called regulatory T cells ("Tregs") ensure that immune responses take place in a coordinated manner: They downregulate the dividing activity of helper T cells and reduce their production of immune...
