Research Interests

My research interests include understanding the factors that may exacerbate or ameliorate the effects of traumatic brain injury (TBI) on neurologic structure and function. To this end, my lab is focused on characterizing and developing tools for investigating ferret TBI models, given that the structure of the ferret brain more closely resembles the human brain than popular rodent models. Our primary area of concentration is on military-relevant injuries, including combined under-vehicle blast and impact TBI as well as TBI + hemorrhagic shock. Ongoing research sponsored by the U.S. Air Force has shown that exposure to low air pressure (hypobaria—modeling air travel) worsens neurologic outcomes after TBI, particularly in the case of repeated exposures. This will inform guidelines for the safe transport of TBI patients.

Research Interests

My research interest is mainly focused on the improvement of patient blood management. Clinically, I am a cardiothoracic anesthesiologist where allogeneic transfusion rates are high. With blood conservation techniques such as acute normovolemic hemodilution, viscoelastic guided transfusion, factor concentrate administration, and alternative blood substitutes bloodless cardiac surgery can be achieved. I have utilized coagulation assessments to monitor the effects of novel agents in clinical and pre-clinical studies. I look to study further allogeneic blood transfusion and its effects on endothelial cell function and its impact on renal function. I also look to study emerging factor replacements and hemostasis monitors for their clinical application.

I am also interested in valvular and left/right ventricular assessment by transesophageal echocardiography. With the improvement in 3D technology, we will be able to determine the operative planning and overall outcomes prior to intervention.

Tibor Kristian, PhD
Professor, Department of Anesthesiology
tkristian@som.umaryland.edu

Research Interests

Research activity in my lab can be divided into two major projects: 1) the role of cell-type-specific mitochondrial dynamics in acute brain injury; (2) disturbed NAD⁺ metabolism and its contribution to the cell death mechanism in neurodegenerative disease. Our recent studies, which utilize transgenic animals expressing cell-type specific mitochondria-targeted fluorescent markers in the brain, show that mitochondria in neurons and astrocytes differentially respond to stress conditions. We first reported that the mitochondria in cells destined to die are not able to re-fuse and regain their pre-insult morphology and functions (Owens et al. 2015) and that both neuronal and astrocytic mitochondria are damaged by excitotoxic insult during ischemic conditions.

It is well established that massive degradation of NAD⁺ can significantly compromise cell survival. Recently, we reported that administering nicotinamide mononucleotide (NMN), a precursor for NAD⁺ synthesis, inhibits NAD⁺ degradation and leads to dramatic protection against ischemic brain injury (Park et al. 2016). We recently revealed that NMN affects several downstream targets that promote the survival of brain cells following pathologic stress (Klimova et al. 2019). We are now characterizing the mechanism of NMN neuroprotection by determining the post-translational modifications of proteins controlling mitochondrial dynamics (Klimova et al. 2020).

Marta Lipinski, PhD

mlipinski@som.umaryland.edu

Research Interests

Autophagy is a catabolic process mediating the turnover of bulk cytoplasmic constituents including organelles and protein aggregates in a lysosome-dependent manner. It is necessary for cellular homeostasis and protects organisms from a variety of diseases, including neurodegeneration and aging. Accumulation of autophagosomes has been observed following traumatic brain injury (TBI) and spinal cord injury (SCI), but its mechanisms and function in those contexts remain unknown. We use in vivo and in vitro models to examine the role of autophagy after TBI and SCI, and to delineate the molecular mechanisms involved. Our data demonstrate that although autophagosomes accumulate in the brain and spinal cord after TBI and SCI, respectively, autophagic degradation cannot proceed to completion. In neurons, this block of autophagy is caused by phospholipase-mediated lysosomal membrane damage and contributes to neuronal cell death. Inhibition of autophagy is also observed in activated microglia and infiltrating macrophages and may contribute to neuroinflammation. We are currently investigating the effects of TBI-induced perturbation in brain lipid homeostasis on microglial and macrophage autophagy and assessing the contribution of the autophagy-lysosomal pathway to delayed development of neurodegeneration and dementia after TBI. Additionally, we are using in vitro models, including human induced pluripotent stem (iPS) cells, to examine the function and mechanisms of USP24, a novel gene associated with Parkinson’s disease (PD). Our long-term goal is to define novel target molecules and pathways for safe and effective modulation of autophagy as a treatment against neurodegeneration induced by both acute (trauma) and chronic (neurodegenerative diseases) causes.

Limiting damage to mitochondria, the primary energy-generating organelles of the cell is crucial for neuroprotection. My laboratory studies basic subcellular mechanisms that govern neuroinflammation and cell death in neurodegenerative disorders, with a focus on mitochondrial bioenergetics. My active projects study the roles of mitochondrial structural and functional remodeling in pro-inflammatory microglial activation, how this neuroinflammatory response exacerbates neuronal injury, and translational strategies for targeting metabolism to promote brain recovery following traumatic brain injury, neonatal hypoxic-ischemic encephalopathy, and in Alzheimer’s disease-related dementias. We have pioneered the development and implementation of two novel applications of Seahorse Bioscience Extracellular Flux Technology, a real-time assessment of mitochondrial respiration within permeabilized brain cells and from whole brain tissue slices, expanding the ways in which mitochondrial function can be studied in cells of the central nervous system.

Chinmoy Sarkar, PhD
Assistant Professor, Department of Anesthesiology
csarkar@som.umaryland.edu

Research Interests

My research interest is focused on understanding the role and function of lipids and cellular organelles in neurodegeneration and neuroinflammation in traumatic brain injury (TBI) and age-associated neurodegenerative diseases. My recent study indicated that the abundance of etherphospholipids, an ether bond containing glycerophospholipids is dysregulated in the mouse cortices after TBI. Etherphospholipids are major components of cellular membrane and play an important role in cellular signaling via their structural impact on the formation and function of lipid rafts. Their synthesis is regulated by the concerted functions of peroxisomes and endoplasmic reticulum. My study shows that etherphospholipids dysregulation after TBI is at least in part caused by the impairment of peroxisomal function. Peroxisomes play an important role in maintaining cellular lipid and redox homeostasis which are disrupted after TBI. Currently, my research is aimed to elucidate its role and function in the pathophysiology of TBI and to develop novel treatment strategy to attenuate neurodegeneration and neuroinflammation after TBI by restoring its function in the injured brain.

Bogdan Stoica, MD
Professor, Department of Anesthesiology
bstoica@som.umaryland.edu

Research Interests

The main focus of my research is to understand the molecular mechanisms of neuronal cell death and neuroinflammation after central nervous system trauma. My studies are based on the hypothesis that brain trauma initiates multiple maladaptive mechanisms (secondary injury) that lead to improper activation of neuronal cell death pathways and/or prevent efficient activation of neuronal repair mechanisms. Thus, neurons that receive a survivable injury are unnecessarily removed and/or fail to undergo effective repair/regeneration. An important driver of these changes is injury-induced dysregulation of microglia responses that shift the microglia post-injury reactive states toward specific persistent pro-inflammatory phenotypes resulting in secondary neurotoxicity.

Areas of special interest include: 1) the modulation of secondary injury mechanisms by microRNAs, a group of regulatory non-coding small RNA molecules following experimental traumatic brain injury (TBI); our recent data suggest that injury-induced changes in specific microRNAs are key to the activation of neuronal cell death pathways and ultimately to neuronal cell loss after TBI; and 2) the transcriptomic changes and their epigenetic underpinning that drive the molecular and cellular secondary injury processes.

By identifying the injury-induced molecular dysfunctions we can design optimal therapeutic approaches that will shift microglia activation toward neurorestorative phenotypes to increase neuronal survival and recovery after brain trauma, thus improving neurological deficits.

Vascular leakage is involved in the pathogenesis of lung permeability in hemorrhage shock/sepsis. We found that fibrinogen, the major component of plasma, binds to heparan sulfate on syndecan-1/glycocalyx forming a gel-like layer that lines the endothelium and maintains vascular barrier integrity. This gel-like layer shields the cleavage sites on syndecan-1/glycocalyx by MMP9, which otherwise cleaves syndecan-1/glycocalyx to cause lung vascular leakage in hemorrhage shock/sepsis.

lzou@som.umaryland.edu

Research Interests

My long-term research focuses on the role of innate immunity in inflammation and organ injuries associated with critical illnesses such as sepsis, shock, and trauma. Our recent findings have identified an increase in plasma cell-free RNA, including miRNAs, during sepsis and trauma. These extracellular RNAs (exRNAs) are released by host cells and their levels are closely correlated with the severity of sepsis. My research aims to test the hypothesis that ex-miRNAs play a critical role in the pathogenesis of acute lung injury and brain inflammation during polymicrobial sepsis. Additionally, we are also investigating whether exRNAs act as molecular drivers that activate innate immunity by modulating macrophage function, potentially contributing to trauma-induced inflammation and organ injury. To explore these mechanisms, we employ a range of complementary approaches, including genetically modified animal models, adoptive cell transfer, chimeric models, synthetic oligonucleotides, pharmacological inhibitors, receptor antagonists, and locked nucleic acid-modified anti-miRNA inhibitors.  The research is supported by NIH R35GM124775 (PI),  R01NS110567 (MPI).
