So followup is needed. Contact your stroke leaders to get this done. Nothing will happen since we have NO stroke leadership.
Brain regulatory T cells suppress astrogliosis and potentiate neurological recovery
Abstract
In addition to maintaining immune tolerance, FOXP3+ regulatory T (Treg) cells perform specialized functions in tissue homeostasis and remodelling1,2. However, the characteristics and functions of brain Treg cells are not well understood because there is a low number of Treg cells in the brain under normal conditions. Here we show that there is massive accumulation of Treg
cells in the mouse brain after ischaemic stroke, and this potentiates
neurological recovery during the chronic phase of ischaemic brain
injury. Although brain Treg cells are similar to Treg cells in other tissues such as visceral adipose tissue and muscle3,4,5, they are apparently distinct and express unique genes related to the nervous system including Htr7, which encodes the serotonin receptor 5-HT7. The amplification of brain Treg
cells is dependent on interleukin (IL)-2, IL-33, serotonin and T cell
receptor recognition, and infiltration into the brain is driven by the
chemokines CCL1 and CCL20. Brain Treg cells suppress
neurotoxic astrogliosis by producing amphiregulin, a low-affinity
epidermal growth factor receptor (EGFR) ligand. Stroke is a leading
cause of neurological disability, and there are currently few effective
recovery methods other than rehabilitation during the chronic phase. Our
findings suggest that Treg cells and their products may
provide therapeutic opportunities for neuronal protection against stroke
and neuroinflammatory diseases.
