Research Topic: Sexual Dimorphic: Expression of Interleukin-1B in Mouse Model of Inflammatory Pain Graduation Year: 2025

Undergraduate Research in the Neighborhoods

Chronic pain is reported to affect at least 10% of the world’s population and about 50.2 million Americans daily; and it is reported to be more prevalent in females than males. Oluwabusola hypothesized that the immune response associated with pain, specifically the expression of IL-1B, will be different between male and female mice. To test this hypothesis, she induced inflammatory pain in adult female and male mice by injecting complete Freund’s adjuvant (CFA) into the pain. CFA is known to induce inflammation and pain; pain sensitivity was measured by von Frey filaments and expression of IL-1B was assessed by qPCR from skin samples. Results include that inflammation resolved faster in male than female mice. Identifying the difference in the sensitivity of pain in males and females may provide ways to further identify how to develop sex-specific treatments and help combat pain more effectively.
