Modulating immune system development and function through microRNA MIR-146

摘要

The present disclosure relates to the finding that microRNA-146 plays a role in modulating the development and function of the immune system. Immune cell development and function can be modulated by delivery of microRNA-146 (miR-146) or antisense miR-146 to target immune cells or precursor cells. For example, in some embodiments, activity and/or proliferation of certain immune cells is regulated by administering miR-146 oligonucleotides or anti-miR-146 oligonucleotides. In other embodiments, pro-inflammatory cytokine expression in immune cells is regulated by administering a miR-146 oligonucleotide or anti-miR-146. In further embodiments, methods of regulating macrophage activity using antisense miR-146 are provided. Additional methods and compositions for regulating immune system function and development using miR-146 are disclosed.
