Toxoplasma Gondii Seropositivity And Risky Behaviors In College-Age Adults, Roohika Rastogi

Undergraduate Student Symposium

Toxoplasma gondii is a prevalent parasite that has infected more than 40 million people in the USA. House cats and other felids serve as definitive hosts and acquire Toxoplasma by consuming infected prey and intermediate hosts (e.g. rodents). Toxoplasma is known to manipulate prey neurophysiology to enhance its transmission. For example, infected rodents exhibit changes in testosterone, vasopressin, and dopamine. These neurophysiological changes elicit remarkable changes in host behavior: Toxoplasma-infected rodents are more likely to frequent open spaces and are less responsive to normally aversive stimuli (e.g. cat urine). The manipulation of intermediate host neurophysiology and behavior observed in …

Developing A Better Animal Model Of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (Me/Cfs), Roberto Fileni, Amanda Lee, Medha Mageswaran

Undergraduate Student Symposium

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a rare but extremely debilitating disease characterized by severe fatigue, even after only mild exertion. In fact, ¼-⅓ of patients are house- or bedridden, underscoring the urgent need for effective treatment. Patients with ME/CFS display hypocortisolism, overactive serotonergic systems, and elevated TGF-β levels, suggesting that ME/CFS includes dysfunction of the endocrine, nervous, and immune systems. Current animal models of ME/CFS use immune activators but lack the complex multisystemic nature of the disease and bear a closer resemblance to depression than ME/CFS. One recent study showed that an adrenalectomy (ADX) better matched the characteristics seen …

Exploring Alternative Binding Locations Of 5-Ht Antagonist Ketanserin In Microtubules; Implications For Future Research, Caleb Siguenza, Tatum Hedrick

Undergraduate Student Symposium

Recently, it’s been demonstrated that classic psychedelic action is mediated via intracellular mechanisms rather than action at membrane receptors. This intracellular action elicits neuroplastic effect. The conclusion is that these effects are due to activation of intracellular 5-HT2AR based on using ketanserin as a selective antagonist based on its selectivity to bind to the membrane 5-HT2A serotonin receptor. However, neuroplasticity is dependent upon multiple mechanisms and signaling cascades including the dynamics of neuronal microtubules. As the targets of ketanserin’s biological intracellular activity are not fully elucidated, here we investigate the binding potential of ketanserin to domains of the microtubule constituent …
