ATP From Sensory Neuron-Interneuron Crosstalk Is Key to Spreading Inflammation in Rheumatoid Arthritis

In rheumatoid arthritis, inflammation in one joint is transmitted to other joints via the sensory neuron connections in the spinal cord, leading to inflammation in the other joints. Inflammation in one joint led to an increase in ATP in other joints, which triggered an increase of a signaling molecule that resulted in inflammation. Blocking the pathway reduced the spread of inflammation.

Brain Tissue Yields Clues to Causes of PTSD

Gene expression patterns in four regions of the prefrontal cortex are distinctly different in those who have been diagnosed with PTSD compared to those who have not. Major differences were seen in interneurons, which inhibit the immune system and microglia in the central nervous system. Findings shed light on why women are more likely to experience PTSD and compound a link between post-traumatic stress and a dampening of the immune system.

Discovery of Gatekeeper Nerve Cells Explains the Effect of Nicotine on Learning and Memory

Researchers discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can help explain our ability to remember and sort information. The newly discovered gatekeeper nerve cells, also called OLM-alpha2 cells, provide an explanation to how the flow of information is controlled in the hippocampus.

This is a fast spiking interneuron in the cerebral cortex of the mouse.
