Neurotensin conjugate provides pain relief in animal models

The small peptide neurotensin is a potent regulator of dopamine signaling and can provide dramatic pain relief; however, the blood brain barrier provides a substantial challenge toward clinical use of neurotensin for analgesia. In this issue of the Journal of Clinical Investigation, Philippe Sarret and colleagues at Université de Sherbrooke generated a conjugate of neurotensin with a peptide able to cross the blood brain barrier and evaluated the analgesic effects of this molecule in animal models of pain. The authors observed efficient transportation of the conjugate (ANG2002) across the blood brain barrier and dose-dependent pain relief in multiple models. The results from this study suggest that ANG2002 has potential to be effective for clinical pain management.

T cell repertoire following hematopoietic stem cell transplant

A promising treatment for hematologic and other malignancies is the transplantation of hematopoietic stem cells isolated from the patient. The use of an individuals own stem cells reduces complications involved with graft rejection;however, many patients develop autoimmune disease or other complications following the procedure. In this issue of the Journal of Clinical Investigation, Laurence Turka and colleagues from Massachusetts General Hospital evaluated the T cell response in a cohort of poor-prognosis MS patients following hematopoietic stem cell transplantation (HSCT) and determined that HSCT had differential effects on T cell repertoire. Importantly, patients with a diverse T cell population following the procedure were more likely to respond well to treatment.
