Macrophages likely to be a potential target for ER+ breast cancer

Most immunotherapies that aim to increase T cell activity are ineffective in treating estrogen receptor-positive (ER+) breast cancer. A new study of invasive ER+ breast cancers led by researchers at the University of Pittsburgh School of Medicine implies that targeting a different type of immune cell called macrophages may be a more effective approach.

Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.
