Does mannan binding lectin-associated serine protease-2 ( MASP-2 ) critically contribute to post-ischemic brain injury independent of MASP-1?
This work demonstrates the essential role of the low-abundant MASP-2 in the mediation of cerebral ischemia-reperfusion injury and demonstrates that targeting MASP-2 by an inhibitory therapeutic antibody markedly improved the neurological and histopathological outcome after focal cerebral ischemia. These results contribute to identifying the key lectin pathway component driving brain tissue injury following cerebral ischemia and call for a revision of the presently widely accepted view that MASP-1 is an essential activator of the lectin pathway effector component MASP-2.
These findings suggest that a high rate of CrBs in the sputum is present in infants with RSV bronchiolitis, and notably the CrBs are associated with the progression to recurrent wheezing and asthma.
