Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, according to new University at Buffalo research that sought to improve understanding of the connection between obesity and gum disease.
Stress can have a significant negative effect on health, but our understanding of how stress impacts the development and progression of cancer is just beginning. A team from Roswell Park Comprehensive Cancer Center has identified an important mechanism by which chronic stress weakens immunity and promotes tumor growth. Their findings, just published in Cell Reports, point to the beta-adrenergic receptor (β-AR) as a driver of immune suppression and cancer growth in response to stress, opening the possibility of targeting this receptor in cancer therapy and prevention.
In a new article published in the journal Immunity, Moffitt Cancer Center researchers reveas how protein-signaling pathways associated with cellular stress processes turn myeloid cells into tumor-promoting players. They also suggest that targeting the PERK protein may be an effective therapeutic approach to reactivate the immune system and boost the effectiveness of immunotherapy.
