Mouse version of 3q29 deletion: insights into schizophrenia/ASD pathways

Emory researchers see investigating 3q29 deletion as a way of unraveling schizophrenia’s biological and genetic Read more

B cells off the rails early in lupus

Emory scientists could discern that in people with SLE, signals driving expansion and activation are present at an earlier stage of B cell differentiation than previously Read more

Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy. The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 Read more

Cancer immunotherapy, meet chimera

In Greek mythology, the chimera was a monstrous fire-breathing creature composed of the parts of three animals: a lion, a snake and a goat.

Adoptive cell transfer is advancing as a cancer immunotherapy technique. It involves removing some of a patient’s immune cells, culturing them in the laboratory, and then infusing the cells back into the patient. The idea is to enhance the ability of the immune cells to attack the tumors far beyond what the immune system was able of doing on its own.

Two promising examples are the National Cancer Institute’s approach of treating advanced melanoma with IL-2-stimulated immune cells, and several investigators’ approach of genetically engineering T cells to attack leukemias or lymphomas.

Jacques Galipeau and colleagues at Winship Cancer Institute have developed a chimeric molecule for stimulating immune cells, which appears to have unique powers beyond simply the sum of its two parts. The molecule is called GIFT4, a fusion of the immune signaling molecules GM-CSF (often used in cancer treatment) and IL-4.
