Phenotype, development, and biological function of myeloid-derived suppressor cells.

CD11bGr-1 myeloid-derived suppressor cells (MDSCs) are an important population of innate regulatory cells mainly comprising monocytic MDSCs (M-MDSCs) with a phenotype of CD11bLy6GLy6C and granulocytic MDSCs (G-MDSCs) with a phenotype of CD11bLy6GLy6C in mice. They play crucial roles in the pathogenesis of cancers, chronic infections, autoimmune diseases, and transplantation. Various extracellular factors such as lipopolysaccharide (LPS), macrophage colony-stimulating factor (M-CSF), granulocyte macrophage colony-stimulating factor (GM-CSF), stem cell factor (SCF), interleukin (IL)-6, interferon gamma (IFNγ), IL-1β, vascular endothelial growth factor (VEGF), Hsp72, IL-13, C5a, and prostaglandin E2 (PGE2) can induce MDSC differentiation, whereas IL-4 and all-trans-retinoic acid can inhibit this process.

Synthesis, crystal structure and biological evaluation of substituted quinazolinone benzoates as novel antituberculosis agents targeting acetohydroxyacid synthase.

Acetohydroxyacid synthase (AHAS) catalyzes the first essential biosynthetic step of branched-chain amino acids and is a biologically safe target against Mycobacterium tuberculosis (MTB). In our previous research, we used virtual screening to identify some novel AHAS inhibitors as potent antituberculosis agents. In this study, we synthesized twenty-four additional quinazolinone benzoates and explored their antitubercular activity.

Hematopoietic stem cell transplantation for treatment of patients with leukemia concomitant with active tuberculosis infection.

Background: Currently, hematopoietic stem cell transplantation is still an essential treatment approach for leukemia. However, patients with leukemia often have weakened immune function, especially more seriously compromised cellular immune response, and appear to be at greater risk for tuberculosis infection during the transplantation process. We aimed to investigate the efficacy and safety of hematopoietic stem cell transplantation for the treatment of patients with leukemia accompanying active tuberculosis infection.
