Anatomy is the field of biology that studies the structure of living things. Anatomy focuses on the composition, structure and location of the parts of organisms tissues, organs and systems as well as the relationships between different parts.
Cholinergic neurons innervate multiple layers in the main olfactory bulb but the precise circuitry of this input is not known. Here the authors show that VGLUT3+ cholinergic neurons selectively innervate deep short axon cells in specific layers and elicit robust monosynaptic GABAergic and nicotinic postsynaptic currents.
Developmental cues for the different dendritic cell (DC) subsets in the intestine are yet to be defined. Here the authors show that TGFβR1 signalling is needed for development of CD103+CD11b+ intestinal DCs from CD103−CD11b+ cells and that they contribute to the generation of Th17 and regulatory T cells
γδ T cells are found mainly in epithelial tissues, where they have crucial roles in tissue homeostasis and repair. Here, the authors describe how γδ T cells are activated and regulated in epithelial tissues, such as the skin and intestine, to mediate host microbial tolerance and provide protection against infection.
Caveolin-1 has a critical role in orchestrating the membrane organization of B cells. In its absence, signaling via the B cell antigen receptor and B cell tolerance are impaired, which results in autoimmunity.
A two-amino-acid substitution in the transcription factor RORγt disrupts its effect in establishing the transcriptional program of TH17 cells while leaving its function in the development of thymocytes and lymphoid-tissue–inducer cells largely intact.
