Natural Autoantibodies: Origin, Function And Utility For Diagnosis Of Disease, Abhirup Sarkar Aug 2019

Natural Autoantibodies: Origin, Function And Utility For Diagnosis Of Disease, Abhirup Sarkar

Graduate School of Biomedical Sciences Theses and Dissertations

Autoantibodies (aAbs) by the simplest definitions have been described as antibodies against self-antigens and were exclusively associated with autoimmune diseases. Eventually, studies demonstrated that they are abundant in the blood of all human sera, regardless of age, gender, or the presence or absence of disease, and were thus named as ‘natural autoantibodies’. The underlying reason for their ubiquity has remained elusive, but we have hypothesized that they are responsible for clearing blood-borne cell and tissue debris generated under conditions of health and disease. To test this, we chose to use two widely different disease model systems, namely neurodegenerative diseases and …

Traumatic brain injury (TBI) is a significant cause of morbidity and mortality in the USA and other developed countries worldwide. Following the initial mechanical insult, the brain’s primary innate immune effector, microglia, initiate inflammatory signaling cascades and pathophysiological responses that can lead to chronic neuroinflammation and neurodegenerative sequelae. The p38α MAPK signaling pathway in microglia is a key contributor to inflammatory responses to diverse disease-relevant stressors and injury conditions. Therefore, we tested here whether microglia p38α contributes to acute and persistent inflammatory responses induced by a focal TBI. We generated conditional cell-specific knockout of p38α in microglia using a CX3CR1 …


Neuroprotective Activity Of Leukemia Inhibitory Factor Is Relayed Through Myeloid Zinc Finger-1 In A Rat Model Of Stroke, Stephanie M. Davis, Lisa A. Collier, Elspeth A. Foran, Christopher C. Leonardo, Craig T. Ajmo Jr., Keith R. Pennypacker Apr 2019

Neuroprotective Activity Of Leukemia Inhibitory Factor Is Relayed Through Myeloid Zinc Finger-1 In A Rat Model Of Stroke, Stephanie M. Davis, Lisa A. Collier, Elspeth A. Foran, Christopher C. Leonardo, Craig T. Ajmo Jr., Keith R. Pennypacker

The aim of this study was to determine whether leukemia inhibitory factor (LIF) exerts its neuroprotective effects through signal transduction of the transcription factor myeloid zinc finger-1 (MZF-1). According to the hypothesis of this study, MZF-1 mediates LIF-induced neuroprotective signaling during ELVO through increased expression and transcriptional activity. To determine the in vivo role of MZF-1 in LIF-induced neuroprotection, we used Genomatix software was used to MZF-1 sites in the promoter region of the rat superoxide dismutase 3 (SOD3) gene. Stroke was induced via middle cerebral artery occlusion, and animals were administered PBS or 125 μg/kg LIF at …


Efficacy Of Leukemia Inhibitory Factor As A Therapeutic For Permanent Large Vessel Stroke Differs Among Aged Male And Female Rats, Stephanie M. Davis, Lisa A. Collier, Sarah J. Goodwin, Douglas E. Lukins, David K. Powell, Keith R. Pennypacker Mar 2019

Preclinical studies using rodent models of stroke have had difficulty in translating their results to human patients. One possible factor behind this inability is the lack of studies utilizing aged rodents of both sexes. Previously, this lab showed that leukemia inhibitory factor (LIF) promoted recovery after stroke through antioxidant enzyme upregulation. This study examined whether LIF promotes neuroprotection in aged rats of both sexes. LIF did not reduce tissue damage in aged animals, but LIF-treated female rats showed partial motor skill recovery. The LIF receptor (LIFR) showed membrane localization in young male and aged rats of both sexes after stroke. …

Background/aim: Autism spectrum disorder (ASD) describes a range of neurodevelopmental disabilities that impair behavior and communication. Although it is relatively prevalent, the pathophysiology is still subject to speculation and debate. The aim of this study is to identify a possible association between interleukin-6, -8, -9, and -10 and tumor necrosis factor alpha (TNF- ∝) in autism among Jordanian children by comparing the plasma levels of these cytokines in autistic children with those of their unaffected siblings and unrelated healthy controls. Materials andmethods: In this study, 80 Jordanian children under the age of 12 with diagnosed autism were selected. For comparison, …
