Abstract
|
|
|
|
Mesenchymal stem cell (MSC) based cell therapy has emerged as a promising therapeutic approach for treatment of several degenerative, infectious and non-infectious diseases. Numerous studies have demonstrated the remarkable immunosuppressive and antibacterial effects of MSCs both in vitro and in vivo, in animal models and in humans. However, the antibacterial effects of MSCs rely heavily on their paracrine factors rather than direct cell-to-cell contact and the effect is specific to disease and site of infection or injury. Furthermore, recent studies have demonstrated the double-edged sword effect of MSCs in bacterial infectious diseases. Despite their inherent potential for repair of damaged tissues, immunosuppression, and alleviation of various autoimmune as well as infectious diseases, MSCs also play a critical role in promoting persistent bacterial infection and disease progression. Therapeutic administration of MSCs successfully inhibited the bacterial growth and enhances survival by improved clearance of pathogenic bacteria in sepsis and pneumonic conditions. However, due to their abnormal transformation, they assist in long lasting survival and persistent infection of Mycobacterium tuberculosis (M. tuberculosis) and may also be responsible for progression of gastric cancer. This review focuses on recent advances that have broadened our understanding of MSC based therapy for bacterial diseases and provides new insight into the possible therapeutic targets of fatal bacterial diseases.
