The complement system drives local inflammatory tissue priming by metabolic reprogramming of synovial fibroblasts

期刊: IMMUNITY, 2021; 54 (5)

Arthritis typically involves recurrence and progressive worsening at specific predilection sites, but the checkpoints between remission and persistenc......

Fibroblast-macrophage reciprocal interactions in health, fibrosis, and cancer

期刊: IMMUNITY, 2021; 54 (5)

Fibroblasts and macrophages are present in all tissues, and mounting evidence supports that these cells engage in direct communication to influence th......

Glycolytic ATP fuels phosphoinositide 3-kinase signaling to support effector T helper 17 cell responses

期刊: IMMUNITY, 2021; 54 (5)

Aerobic glycolysis-the Warburg effect-converts glucose to lactate via the enzyme lactate dehydrogenase A (LDHA) and is a metabolic feature of effector......

Golgi apparatus-synthesized sulfated glycosaminoglycans mediate polymerization and activation of the cGAMP sensor STING

期刊: IMMUNITY, 2021; 54 (5)

Activation of the cyclic guanosine monophosphate (GMP)-AMP (cGAMP) sensor STING requires its translocation from the endoplasmic reticulum to the Golgi......

SARS-CoV-2 exacerbates proinflammatory responses in myeloid cells through C-type lectin receptors and Tweety family member 2

期刊: IMMUNITY, 2021; 54 (6)

Despite mounting evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) engagement with immune cells, most express little, if any, o......

Analysis of SARS-CoV-2 variant mutations reveals neutralization escape mechanisms and the ability to use ACE2 receptors from additional species

期刊: IMMUNITY, 2021; 54 (7)

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants continue to emerge during the global pandemic and may facilitate escape from cur......

Cytoplasmic DNA sensing by KU complex in aged CD4(+) T cell potentiates T cell activation and aging-related autoimmune inflammation

期刊: IMMUNITY, 2021; 54 (4)

Aging is associated with DNA accumulation and increased homeostatic proliferation of circulating T cells. Although these attributes are associated wit......

GPR34-mediated sensing of lysophosphatidylserine released by apoptotic neutrophils activates type 3 innate lymphoid cells to mediate tissue repair

期刊: IMMUNITY, 2021; 54 (6)

Neutrophils migrate rapidly to damaged tissue and play critical roles in host defense and tissue homeostasis. Here we investigated the mechanisms wher......

Environmental enteric dysfunction induces regulatory T cells that inhibit local CD4+T cell responses and impair oral vaccine efficacy

期刊: IMMUNITY, 2021; 54 (8)

Environmental enteric dysfunction (EED) is a gastrointestinal inflammatory disease caused by malnutrition and chronic infection. EED is associated wit......
