Achieving immune tolerance through cell transplantation is a promising approach for treating autoimmune disease. In this issue of Cell Stem Cell, Akiyama et al. (2012) demonstrate that human and mouse mesenchymal stem cells can induce immune suppression by attracting and killing autoreactive T cells, which stimulates TGFb production by macrophages ...

Cancer immunotherapy holds great promise, yet its efficacy and applicability can be hampered by the rise of systemic toxicities. We have recently shown that the lethal side effects of cancer immunotherapy are markedly exacerbated with aging. Blocking tumor necrosis factor α or macrophages can alleviate the systemic toxicity of immunotherapy while p...

Our understanding of NK biology has expanded immensely since the initial discovery of natural killer cells in 1975. New studies have uncovered various levels of immune regulation both on and by unique subsets of NK cells, which go well beyond simple receptor-ligand interactions between NK cells and target cancer cells. Distinct suppressor and effec...

A serious dichotomy currently exists in hematopoietic stem cell transplantation (HSCT) and cancer research. Cancer is a disease that predominantly affects older people, yet there is a paucity of cancer research addressing the very unique needs of this population. Even basic biologic processes that exist in aging (decline in immune competency, incre...

Novel therapies for chronic graft-versus-host disease (cGVHD) are needed. Aberrant B-cell activation has been demonstrated in mice and humans with cGVHD. Having previously found that human cGVHD B cells are activated and primed for survival, we sought to further evaluate the role of the spleen tyrosine kinase (Syk) in cGVHD in multiple murine model...
