Immunomodulatory effects
MSCs have been shown to exert immunomodulatory effects by interacting with various immune cells. They can suppress the proliferation and function of T cells, B cells, natural killer cells, and dendritic cells.
By secreting anti-inflammatory cytokines such as interleukin-10 (IL-10) and transforming growth factor-beta (TGF-β), MSCs contribute to the regulation of immune responses. This unique ability makes them promising candidates for treating inflammatory and autoimmune conditions.
Antimicrobial activity
Mesenchymal stem cells (MSCs) exhibit antimicrobial activity, which means they can combat various types of microorganisms. These cells have been shown to possess the ability to fight off bacteria, viruses, and fungi by producing specific proteins and peptides that can inhibit their growth and spread.
This antimicrobial property makes MSCs a promising candidate for combating infectious diseases and supporting the body’s immune response. Researchers are exploring the potential of using MSCs in developing new therapies for antibiotic-resistant infections, such as methicillin-resistant Staphylococcus aureus (MRSA), and other challenging microbial conditions.
Furthermore, studies have demonstrated that MSCs can enhance the body’s natural defence mechanisms against pathogens. They do this by modulating the immune system’s responses and regulating inflammatory processes to help contain infections more effectively.
The antimicrobial activity of MSCs opens up exciting prospects for addressing infectious diseases and finding innovative solutions for managing microbial-related health challenges.
