Abstract
In this study, we sought to improve ligament healing by modulating the inflammatory response after acute injury through the neutralization of Interleukin-17 (IL-17), which we hypothesized would decrease inflammatory cell infiltration and cytokine production. Administration of an Interleukin-17 neutralizing antibody (IL-17 NA) immediately following a rat medial collateral ligament (MCL) transection resulted in alterations in inflammatory cell populations and cytokine expression within the healing ligament, but did not reduce inflammation. Specifically, treatment resulted in a decrease in M2 (antiinflammatory) macrophages, an increase in T cells, and an increase in the levels of IL-2, IL-6, and IL-12 in the MCL 7 days post injury. IL-17NA treatment, and subsequent immunomodulation, did not result in improved ligament healing, as measured by collagen composition and wound size.
