CRMP2-binding compound, edonerpic maleate, accelerates motor function recovery from brain damage

A small molecule for stroke therapy Better therapies for motor impairments after stroke are greatly needed. In mice and nonhuman primates, Abe et al. found that edonerpic maleate enhanced synaptic plasticity and functional recovery after a traumatic insult to the brain (see the Perspective by Rumpel). This recovery of motor function was accompanied by functional reorganization of the cortex.

Transcription Factor IRF8 Governs Enhancer 1 Landscape Dynamics in Mononuclear Phagocyte Progenitors

Monocytes and dendritic cells (DCs), mononuclear phagocytes essential for immune responses, develop from hematopoietic stem cells via monocyte–DC progenitors (MDPs). The molecular basis of their development remains unclear. Because promoter-distal enhancers are key to cell-fate decisions, we analyzed enhancer landscapes during mononuclear phagocyte development in vivo. Monocyte- and DC-specific enhancers were gradually established at progenitor stages before the expression of associated genes.

Angiotensin II Type 1 Receptor-associated Protein Inhibits Angiotensin II-induced Insulin Resistance with Suppression of Oxidative Stress in Skeletal Muscle Tissue

Enhancement of AT1 receptor-associated protein (ATRAP) in adipose tissue improves high fat diet (HFD)-induced visceral obesity and insulin resistance, and suppresses adipose oxidative stress. However, HFD loading is not a direct stimulatory factor for AT1 receptor. In the present study, we investigated the effect of chronic, low-dose angiotensin II (Ang II) stimulation on glucose and lipid metabolism in mice and functional role of ATRAP.

Human iPSC Derived Posterior Gut Progenitors Are Expandable and Capable of Forming Gut and Liver Organoids

Early endoderm progenitors naturally possess robust propagating potential to develop majority of meter-long gastrointestinal tracts and are therefore considered as a promising source for therapy. Here, we demonstrated the reproducible generation of human CDX2+ posterior gut endoderm cells (PGECs) from five induced pluripotent stem cell clones by manipulating FGF, TGF and Wnt signaling.
