Research Interests

Neonatal anemia; murine RBC-transfusion; Necrotizing Enterocolitis; Retinopathy of Prematurity; retinal inflammation; Leukocyte Biology and functions more


Dr. Krishnan, Assistant Professor, received his Ph.D. in Biochemistry-Biotechnology from the University of Madras in 2008.  He completed his postdoctoral fellowship in the Department of Pediatrics at the University of Alabama at Birmingham and Department of Pediatrics, University of Illinois at Chicago. After he worked as Research Associate in Department of Pediatrics at the University of South Florida, Dr. Krishnan joined the faculty at JHU in May 2018. His lab investigates the pathophysiology of Transfusion-associated Necrotizing Enterocolitis (TANEC) and Systemic Inflammatory Response Syndrome (SIRS) in premature infants who are at high risk of anemia and heavily transfused.  Dr. Krishnan is dedicated to understanding the role of monocyte/macrophage in the neonate and investigating their inflammatory phenotype, function during anemia and/or RBC-transfusion associated NEC and SIRS. more

Research Summary

Mohan Krishnan’s research interests focus on the inflammatory mechanisms of neonatal necrotizing enterocolitis (NEC), specifically on red blood cell (RBC) transfusion-associated NEC. Dr. Krishnan is currently the PI of NIH-R21 project entitled "RBC transfusion in anemic neonates leads to systemic inflammatory response syndrome" and PI  (interim) of two NIH-R01 project entitled "Effect of Platelet Transfusions on Neonatal Intestinal Injury". Dr. Krishnan is interested in the role of monocyte/macrophage in NEC pathogenesis, developed a preclinical mouse model of RBC transfusion-associated NEC and recently published in Nature Communications. This novel model of transfusion-associated NEC is the first preclinical model of transfusion effects in the neonatal intestine and has been awarded a provisional patent. He laid the groundwork for these preclinical models to understand the mechanism(s) by which anemia-transfusion causing gut/systemic inflammation in neonates, a critical step in the development of novel anti-inflammatory therapies that can prevent/ameliorate tissue damage. By focusing on red blood cell biology and transfusion medicine, he increasingly appreciates shared molecular mechanisms driving transfusion-associated adverse effects such systemic inflammatory response syndrome (SIRS) and NEC.
