Augusta University President Brooks A. Keel, PhD, announced the formation of this new transdisciplinary faculty research cluster in “inflammaging” and brain aging, which will be the focus of a three-year recruitment effort to grow the university’s research footprint.
As people get older, they experience a low-level of inflammation, described as “inflammaging,” driven by an increase in molecules in the blood called cytokines. This age-related inflammation has been linked to serious chronic diseases, including Alzheimer’s disease, cardiovascular disease, atherosclerosis, type II diabetes and cancer. The main feature of the aging process is chronic and progressive inflammation, which is a significant risk factor in morbidity and mortality. While most age-related diseases include inflammation, its potential cause and role in adverse health outcomes is still widely unknown.

We have discovered that activating the basal forebrain cholinergic pathways makes animals smarter. These pathways are intrinsic to the regulation of higher cognitive function, and decline with aging and Alzheimer’s dementia. Our work in young and aged nonhuman primates has shown activating these pathways improves working memory and sustained attention task performance. Our work in the mouse model has shown that activation improves spatial memory, and correspondingly improves levels of brain neurotrophins while decreasing levels of beta amyloid. Human trials are planned. This work, spanning from rodent to monkey to human, is designed to optimize bench-to-bedside translation to treat cognitive decline in dementias.

Dr. Deak’s research is focused on synapses, the key units in information processing in the brain. Cognitive decline in Alzheimer's disease is thought to be the result of disturbed neuronal communication due to synaptic dysfunction. One major disease hallmark is aggregated amyloid beta protein, which accumulates in senile plaques in AD. To identify the molecular process leading to impaired neuronal communication, we apply sophisticated behavioral, system and cellular assays in a series of studies. For instance, we investigate why aging is the most relevant risk factor to Alzheimer’s dementia. We test the age-related changes in a set of essential synaptic proteins, which regulate vesicular neurotransmitter release from synapses and their effect on beta-amyloid secretion. Maintaining physiological synaptic function while reducing amyloid secretion may provide a breakthrough to design effective therapies that halt progression of dementia in Alzheimer's disease.
Periodontitis (PD) is a chronic disease of aging that affects 7 out of every 10 Americans over 65 years old, and has been linked to increased risk of other age-related diseases such as Alzheimer’s disease. Increased accumulation of senescent cells with a characteristic senescence-associated secretory phenotype (SASP) occurs with advanced age, contributing to inflammaging and the pathophysiology of age-related diseases. Our laboratory has recently identified a novel pathogenic mechanism for initiation and amplification of immune senescence and alveolar bone loss in PD via microbially-induced dendritic cell SASP exosomes. My laboratory is dissecting the molecular mechanisms of age-related and microbially-induced SASP exosomes in periodontal disease. Exosomes can travel to distant sites and have been shown to pass through the blood-brain barrier. Thus, we are interested to study the role of microbially-induced SASP exosomes associated with PD in the development of systemic diseases such as Alzheimer’s. We anticipate an important outcome of these studies to be the identification of novel diagnostic biomarkers and senolytic therapies for periodontitis and other age-related diseases to warrant a healthy aging to our population.
Our laboratory is interested in exploring the impact of cardiovascular diseases on the functional integrity of the neurovascular unit. We showed that in addition to the canonical neuron-to-vascular signaling modality (neurovascular coupling), changes in vascular reactivity alter basal neuronal firing activity, a phenomenon we defined as vasculo-neuronal coupling. We hypothesize that impaired vasculo-neuronal coupling is an early event in vascular cognitive impairment and dementia. Using state of the art techniques, current studies are focused on defining the molecular mechanisms by which cardiovascular risk factors such as hypertension, increased blood pressure variability, and heart failure decouple intercellular communication between vascular cells, glial cells and neurons.

Dr. Fulzele's laboratory is investigating the role of micronutrients (Vitamin C, Arginine, and Tryptophan) in stem cell function and its direct correlation with age-related musculoskeletal complications. Dr. Fulzele's laboratory identified the expression of a functionally active vitamin C transporter (in stem cells) and its modulation with age. Dr. Fulzele's lab also demonstrated an important role of Arginase 1 in muscle and bone biology with age. Furthermore, in collaboration with the Bone group, they discovered the negative role of the tryptophan-kynurenine pathway in age-associated musculoskeletal complications (stem cell dysfunction, muscle, and bone loss). Dr. Fulzele's laboratory also investigates the critical role of the miRNAs and exosomes (EVs) in stem cell biology and cartilage tissue engineering. Dr. Fulzele is interested in defining how age alters the secretion and cargo of EVs in a sex- and hormone-specific manner and identifying the role of EV in the pathogenesis of musculoskeletal with age. During the last one and half years, Dr. Fulzele's laboratory has performed pioneering work on how COVID-19 affects aged populations. Dr. Fulzele identified several miRNAs targeting covid19 genome downregulated with age. Dr. Fulzele also showed a strong association between nasal microbiota composition and SARS-CoV-2 infection and severity in aged patients.

Pain-related functional impairment (e.g. impairment in performance of daily activities) is a public health problem that affects the quality of life of many individuals, particularly older adults. A critical barrier to progress in improving the understanding and treatment of pain-related functional impairment is over-dependence on preclinical research methods that rely on quantification of simple, reflexive behavioral responses to pain stimuli instead of quantifying clinically-relevant pain-related disruption of behavior. Our laboratory has developed rodent models of pain-related disruption of behavior that are being used to examine age-related differences in sensitivity to pain-related functional impairment, and age-related differences in effectiveness and potency of established and candidate analgesics. Our goal is to bridge gaps in our understanding of the role of aging and other variables in pain-related functional impairment, and contribute to the development of new, safe, and effective analgesics.

Dr. NeSmith is Professor and Chair of the Department of Nursing Science and Director of the Nursing PhD Program at Augusta University. With experience in trauma, emergency, and disaster nursing, Dr. NeSmith and her interdisciplinary team of researchers apply the concept of inflammaging to explain effects of lifetime chronic stress on the inflammatory response and how it impacts healing and vulnerability to complications following acute life-threatening injury. Dr. NeSmith and the Trauma Interdisciplinary Group for Research (TIGR) recently published work from a completed funded study in which they compared physiologic measures of chronic stress to differences in the inflammatory response following trauma, and associated outcomes of inflammatory origin like sepsis and organ failure. Dr. NeSmith and the TIGR team base their work on biobehavioral frameworks such as Psychoneuroimmunology, the Weathering Hypothesis, and the Vulnerable Populations Conceptual Framework. These evidence-based frameworks address links between social determinates of health and the stress and inflammatory physiology which ages us in advance of chronology. Dr. NeSmith’s research may lead to advances in surveillance and tailoring individual treatments to prevent and improve acute outcomes of trauma.

Blood vessels undergo a process of vascular remodeling during the natural process of aging. The remodeling is a change in the structure, the thickness, and the size of the blood vessel that can affect circulation to important body organs. During the decades of life, blood pressure, cholesterol, and glucose increase in the bloodstream; these increases are sensed by the endothelial lining of arteries to initiate the process of remodeling. While the change in arterial structure may at first be a functional adaptation, the remodeling can ultimately progress to artery and end-organ disease and pathology. Our basic science lab is examining vascular remodeling and how it is influenced by the time of day through a molecular timekeeper called Bmal1. Further, we seek to examine if age-dependent remodeling has a deeper influence on the aging brain and its memory center using experimental model systems.

Aging is associated with increased inflammation, decline in immune function, bone loss and marrow fat accumulation. Bone marrow is where mesenchymal stem cells (MSCs) and hematopoietic stem cells (HSCs) reside and interact and where adult hematopoiesis takes place. PPARg is a key transcription factor regulating adipocyte differentiation and its expression increases with aging, thus by increasing marrow adipocytes, PPARg exerts impact on bone, inflammation, and hematopoietic reconstitution.

Dr. Singh’s laboratory studies molecular and cellular mechanisms of generation of antibody responses against pathogens and vaccines. Following the infection, antigen (expressed by pathogens) specific B cells develop into plasma cells. Plasma cells are factory for producing antibodies molecule that neutralize the invading pathogens. A single plasma cell produces approximately ten thousand antibody molecule per second. Dr. Singh’s laboratory found that Ufbp1/DDRGK1, an essential component of ufmylation pathway plays an essential role in development of plasma cells. Plasma cells possess a dense network endoplasmic reticulum, an organelle (chamber), where antibody molecules are synthesized and folded before their secretion. Dr. Singh also showed that Ufbp1 is required for development of endoplasmic reticulum network in plasma cells. Currently, he is exploring the mechanisms how Ufbp1 and other components of ufmylation pathway regulate development and function of plasma cells. Survival of plasma cells is directly linked to the longevity of protection a vaccine offers. Have you ever wondered why do we take some vaccines such as MMR only once in our life time, whereas we take DTAP vaccine every 5-10 years? Recently, we are advised to take COVID vaccine/boosters every 6-12 months or so. The reason is the longevity of plasma cell induced by these vaccines. Plasma cells induced by MMR vaccine survive for our life time, whereas those induced by DTAP survive for 5-10 years. One of the reasons for frequent COVID vaccine boosters is the emergence of new strains. The second reason is that plasma cells induced by COVID vaccine start dying in approximately 6-7 months or so. Once the plasma cells die, the antibodies produced by them also disappear, which necessitates the requirement of booster shots. Dr. Singh is also studying the factors and mechanisms that regulate the survival of plasma cells. It is well known that vaccines do not induce a potent immune response in elderly population. He is also interested in identifying the mechanisms and factors that can boost the vaccine induced immune responses in aged population. His other research interests include the how T cells are activated and generate immune responses and help other immune cells to successfully eliminate invading pathogens and cancers. Previously he discovered the mechanism underlying dietary fiber mediated suppression of intestinal inflammation and cancers.

Our long-term research goal is to identify the molecular mechanisms of how environmental factors, including fluoride and PFAS, cause adverse effects on craniofacial development and aging. Fluoride is beneficial for reducing and controlling tooth decay and promoting oral health. However, ingesting too much fluoride over a long period can cause health issues, including dental/skeletal fluorosis. Previously we demonstrated that anti-aging gene SIRT1 (silent mating type information regulation 2 homolog) is activated as an adaptive response against fluoride-mediated cell stress. Our current projects include 1) identifying the role of SIRT1 during tooth development, 2) characterizing the epigenetic and non-epigenetic functions of SIRT1 in fluoride-mediated cell stress in amelogenesis and 3) analyzing the age-related fluoride susceptibility.

Dr. Kumar Vaibhav’s lab is dedicated to explore the mechanism behind immune cells activation and senescence post-brain injury. They have found that immune cells, especially macrophages, T cells and innate lymphoid cells, can be polarized to pro-inflammatory states after injury, which leads to long-term chronic injury and neurological deficits. Autophagy and metabolic activity play important role in immune function, as evident from role of AMPK in their published articles. The lab further reported that modulation of cannabinoid system helps immensely to maintain the equilibrium between different polarized states of immune cells and thus, expediting the recovery from injury. However, PI emphasizes that there is a lot more to explore related to brain injury and role of cannabinoid system in homeostasis. Current research in the lab is focused on inflammaging after months of TBI. Lab reports that immunosenescence is one of crucial factor in causing chronic neurodegeneration. The lab is funded through several NIH extramural awards and is actively involved in studies related to cannabinoid and non-cannabinoid system in Traumatic brain injury (TBI) and Intracerebral hemorrhages (ICH).
