The role of cancer cell-released extracellular vesicles: have we become closer to cancer pain treatment?

The effective management of cancer pain continues to be a challenge because of our limited understanding of cancer pain mechanisms and, in particular, how cancer cells interact with neurons to produce pain. In a study published in , Inyang used a mouse model of human papillomavirus (HPV1)-induced oropharyngeal squamous cell carcinoma to show a role for cancer cell-derived extracellular vesicles (cancer sEVs) in cancer pain. They found that inhibiting the release of sEVs reduced spontaneous and evoked pain behaviors, and that pain produced by sEVs is due to activation of TRPV1 channels.

Postnatal deletion of Phlpp1 in chondrocytes delays post-traumatic osteoarthritis in male mice.

Objective: Osteoarthritis is a chronic, debilitating disease that causes long-term pain and immobility. Germline deletion of Phlpp1 or administration of small molecules that inhibit Phlpp1 prevents post-traumatic osteoarthritis (PTOA) in mice. However, the chondrocyte-intrinsic role of Phlpp1 in PTOA progression is unknown.
