Mafb and c-Maf transcription factor (TF) expression is enriched in medial ganglionic eminence (MGE) lineages, beginning in late-secondary progenitors and continuing into mature parvalbumin (PV) and somatostatin (SST) interneurons. However, the functions of Maf TFs in MGE development remain to be elucidated. Herein, Mafb and c-Maf were conditionally deleted, alone and together, in the MGE and its lineages. Analyses of Maf mutant mice revealed redundant functions of Mafb and c-Maf in secondary MGE progenitors, where they repress the generation of SST cortical and hippocampal interneurons. By contrast, Mafb and c-Maf have distinct roles in postnatal cortical interneuron (CIN) morphological maturation, synaptogenesis, and cortical circuit integration. Thus, Mafb and c-Maf have redundant and opposing functions at different steps in CIN development.

Neurons develop diverse synapses that vary in content, morphology, and size. Although transcriptional regulators of neurotransmitter identity are known, it remains unclear how synaptic features are patterned among neuronal subtypes. In the auditory system, glutamatergic synaptic properties vary across three spiral ganglion neuron (SGN) subtypes that collectively encode sound.

Liposomal drug delivery systems have revolutionized traditional cytotoxic drugs. However, the relative instability and toxicity of the existing liposomal drug delivery systems compromised their efficacy. Herein, we present Rg3-lipo, an innovative drug delivery system using a glycosyl moiety-enriched ginsenoside (Rg3).

As crucial phagocytes of the innate immune system, macrophages (Mϕs) protect mammalian hosts, maintain tissue homeostasis and influence disease pathogenesis. Nonetheless, Mϕs are susceptible to various pathogens, including bacteria, viruses and parasites, which cause various infectious diseases, necessitating a deeper understanding of pathogen-Mϕ interactions and therapeutic insights. Pluripotent stem cells (PSCs) have been efficiently differentiated into PSC-derived Mϕs (PSCdMϕs) resembling primary Mϕs, advancing the modelling and cell therapy of infectious diseases.

Landmark discovery of eye defects caused by Pax6 gene mutations in humans, rodents, and even fruit flies combined with Pax6 gene expression studies in various phyla, led to the master control gene hypothesis postulating that the gene is required almost universally for animal visual system development. However, this assumption has not been broadly tested in genetically trackable organisms such as vertebrates. Here, to determine the functional role of the fish orthologue of mammalian Pax6 in eye development we analyzed mutants in medaka Pax6.
