Surface saturation of drug-loaded hollow manganese dioxide nanoparticles with human serum albumin for treating rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory joint disease accompanied by energy depletion and accumulation of reactive oxygen species (ROS). Inorganic nanoparticles (NPs) offer great promise for the treatment of RA because they mostly have functions beyond being drug carriers. However, conventional nanomaterials become coated with a protein corona (PC) or lose their cargo prematurely , reducing their therapeutic efficacy.

Multifunctional nanoparticles inhibit tumor and tumor-associated macrophages for triple-negative breast cancer therapy.

Hypothesis: Tumor-associated macrophages (TAM) are the mainstay of immunosuppressive cells in the tumor microenvironment, and elimination of M2-type macrophages (M2-TAM) is considered as a potential immunotherapy. However, the interaction of breast cancer cells with macrophages hinders the effectiveness of immunotherapy. In order to improve the efficacy of triple-negative breast cancer (TNBC) therapy, strategies that simultaneously target the elimination of M2-TAM and breast cancer cells may be able to achieve a better therapy.

Stress-enhanced cardiac lncRNA Morrbid protects hearts from acute myocardial infarction.

Myeloid RNA regulator of Bim-induced death (Morrbid) is a newly identified leukocyte-specific long noncoding RNA (lncRNA). However, the expression and biological functions of Morrbid in cardiomyocytes and heart disease are currently unclear. This study was meant to determine the role of cardiac Morrbid in acute myocardial infarction (AMI) and to identify the potential cellular and molecular mechanisms involved.
