Could interleukin-33 and its suppressor of tumorigenicity 2 (ST2) receptor have a role in cervical human papillomavirus (HPV) infections?

Why most women can clear human papillomavirus HPV) infections while others can develop permanent infections. The stimulation of immunotolerance of the immune system of the host by the persistent HPV infection may be the answer to this question. Interleukin-33 (IL-33) may play a role in the pathogenesis of HPV infection, this hypothesis was thought to be due to the rapid release of IL-33 from damaged cells following tissue damage, necrosis, and activation of the inflammasome.
