SWOG 1609 cohort 48: anti-CTLA-4 and anti-PD-1 for advanced gallbladder cancer.

Introduction: Most patients with advanced gallbladder cancer are treated with multiagent chemotherapy. Immune checkpoint inhibitors offer the possibility of a durable response with less toxicity. This prospective, multicenter, open-label study was designed to evaluate the anticancer activity of nivolumab plus ipilimumab in patients with advanced gallbladder cancer.

Targeting the tamoxifen receptor within sodium channels to block osteoarthritic pain.

Voltage-gated sodium channels (Na) in nociceptive neurons initiate action potentials required for transmission of aberrant painful stimuli observed in osteoarthritis (OA). Targeting Na subtypes with drugs to produce analgesic effects for OA pain management is a developing therapeutic area. Previously, we determined the receptor site for the tamoxifen analog N-desmethyltamoxifen (ND-Tam) within a prokaryotic Na.

Regenerative capacity in the lamprey spinal cord is not altered after a repeated transection.

The resilience of regeneration in vertebrates is not very well understood. Yet understanding if tissues can regenerate after repeated insults, and identifying limitations, is important for elucidating the underlying mechanisms of tissue plasticity. This is particularly challenging in tissues, such as the nervous system, which possess a large number of terminally differentiated cells and often exhibit limited regeneration in the first place.
