CD47 is a cell surface receptor expressed on many cells in the body. It has many immune functions such as marking host cells as “self” and the activation of apoptosis through phagocytosis. Mac-1 is a major integrin on myeloid cells and has been implicated in several different macrophage immune functions. Previous studies from Dr. Ugarova’s lab demonstrated CD47 may form a complex with Mac-1 through the cis-interaction and could regulate Mac-1-dependent macrophage functions. To localize the binding site for Mac-1 in CD47, the extracellular domain of CD47 IgV was isolated as GST-fusion protein from E. coli cells. The recombinant fusion protein is being used in current studies with cell adhesion assays and immunoprecipitation to determine the complementary binding site in Mac-1.
Social isolation in early childhood can have life-long effects on social behaviors and development. Cerebellar crus I has additionally been linked to social behaviors through forebrain pathways. In this study, we hypothesized that social isolation of mice from postnatal day 21 (P21) until p35 would result in impaired social behaviors. Additionally, we hypothesized that gq DREADD injections into crus I, to increase levels of cerebellar stimulation, at the start of the isolation period would counteract the effects of isolation, leading to mice who displayed normal social behaviors. Social behavior at P35 was tested using the 3-Chamber Task, a well-established model, and SLEAP deep-learning software was used to obtain quantifiable data. We found no difference in social behaviors between socially raised and isolated mice. However, gq DREADD mice displayed greater levels of social interaction and exploration than either socially raised mice or isolated mice. This research carries implications for possible therapeutic interventions for groups prone to social isolation, such as those with developmental disabilities, minority groups, the elderly, and prison populations.

The Founders Lab is a team-focused, exploratory Barrett Thesis project that allows students the opportunity to discover and utilize their “inner entrepreneur”. This project empowers teams of students to come up with a business idea; create a strategic business model; conduct research on a target market; generate a brand style, logo, and other marketing-related materials; meet with business professionals as a way to receive feedback; and finalize a business plan with tangible deliverables. This project in particular focuses on the creation of an app that allows users to connect with others in competitive esports tournaments and participate in tutoring sessions for financial incentives. Throughout our experience participating in the Founders Lab, we were able to construct this business pitch.
