Tim-3: An activation marker and activation limiter of innate immune cells
Frontiers in Immunology, 2013 Tim-3 was initially identified on activated Th1, Th17, and Tc1 cells and induces T cell death or exhaustion after binding to its ligand, Gal-9. The observed relationship between dysregulated Tim-3 expression on T cells and the progression of many ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

The role of natural killer cells in adaptive immune responses [PDF]
Human natural killer (NK) cells have been shown to respond to numerous pathogenic stimuli, producing IFN-y as well as cytolytic effector molecules such as perforin and granzymes.

Leprosy and Immune System An Insight into the Innate Immune System [PDF]
, 2021 Innate immunity is a host immune mechanism to defend itself promptly. It includes physical and chemical barriers, cells in the circulation and tissues, several plasma proteins, and immune cells constituting phagocytic cells (monocytes/macrophages and ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Immune checkpoints on innate lymphoid cells [PDF]
Journal of Experimental Medicine, 2017 In this issue of JEM, Taylor et al. (https://doi.org/10.1084/jem.20161653) describe PD-1 as a critical negative regulator of group 2 innate lymphoid cells (ILC-2s). PD-1 intrinsically controls proliferation and cytokine production of both mouse and human ILC-2s.

Innate Immune Sensing by Cells of the Adaptive Immune System [PDF]
Frontiers in Immunology, 2020 Sensing of microbes or of danger signals has mainly been attributed to myeloid innate immune cells. However, T and B cells also express functional pattern recognition receptors (PRRs). In these cells, PRRs mediate signaling cascades that result in different functions depending on the cell's activation and/or differentiation status, on the environment ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Innate Lymphoid Cells in Mucosal Immunity [PDF]
Frontiers in Immunology, 2019 Innate lymphoid cells (ILCs) are innate counterparts of T cells that contribute to immune responses by secreting effector cytokines and regulating the functions of other innate and adaptive immune cells. ILCs carry out some unique functions but share some tasks with T cells.
