New insight into the immunomodulatory mechanisms of Tretinoin in NMRI mice
Objective(s):Recent evidence have proposed that Tretinoin produced in the gut preferentially promote differentiation of FoxP3+Treg cells but inhibits Th17 lymphocytes, and this may be the main immunomdulatory mechanism of Tretinoin in vivo. This study was done to investigate the effects of Tretinoin in outbred white mice after challenge with sheep red blood cells (SRBC). Materials and Methods:...
متن کاملCrystallographic Insight into Collagen Recognition by Discoidin Domain Receptor 2
The discoidin domain receptors, DDR1 and DDR2, are widely expressed receptor tyrosine kinases that are activated by triple-helical collagen. They control important aspects of cell behavior and are dysregulated in several human diseases. The major DDR2-binding site in collagens I-III is a GVMGFO motif (O is hydroxyproline) that also binds the matricellular protein SPARC. We have determined the c...
متن کاملMechanisms of resistance to quinolones.
The increased use of fluoroquinolones has led to increasing resistance to these antimicrobials, with rates of resistance that vary by both organism and geographic region. Resistance to fluoroquinolones typically arises as a result of alterations in the target enzymes (DNA gyrase and topoisomerase IV) and of changes in drug entry and efflux. Mutations are selected first in the more susceptible t...
