Researchers have discovered that cancer cells use specific chemokines to create a survival niche in the lymph nodes and spleen, allowing them to grow and develop. This niche is created by the interaction between cancer cells and stromal cells, which secrete increased quantities of chemokines CCL19/CCL21.
Researchers at U-M have developed a new diagnostic tool to predict bronchiolitis obliterans syndrome (BOS), the leading cause of death for lung transplant recipients. A high stem cell count after transplantation is linked to an increased risk of developing BOS.
Scientists have found that chronic lymphocytic leukemia (CLL) cells become resistant to chemotherapy by growing among normal cells in the bone marrow and lymph nodes. This resistance is linked to alterations in Bcl-2 family proteins, which makes CLL cells less susceptible to treatment.
A new study from Massachusetts General Hospital finds that circulating tumor cells prepare a hospitable environment for tumor growth by bringing along noncancerous cells, facilitating metastasis. The presence of these supporting cells is crucial for the initial growth and survival of tumors at a new site.
Researchers at the University of Cambridge have discovered that a type of stromal cell found in many cancers expresses fibroblast activation protein alpha, which suppresses the immune response. Destroying these cells allows the immune system to control tumours, paving the way for improved immunological therapies.
Researchers have discovered a mechanism to detect bacteria in the womb, opening up new possibilities for preventative treatments. This unique environment relies on a simpler form of immunity called the innate system, as the adaptive response is underdeveloped.
