Restoring Metabolism of Myeloid Cells Reverses Cognitive Decline in Aging

Scientists showed that in aging mice myeloid cell bioenergetics were suppressed in response to increased signaling by the lipid messenger prostaglandin E2, a major modulator of inflammation.

SOX-5 Activates a Novel RORγt Enhancer To Facilitate Experimental Autoimmune Encephalomyelitis by Promoting Th17 Cell Differentiation

Scientists identified a novel enhancer of RORγt gene in Th17 cells, RORCE2. RORCE2 deficiency suppressed RORγt expression and Th17 differentiation, leading to reduced severity of experimental autoimmune encephalomyelitis.

Designed PKC-Targeting Bryostatin Analogs Modulate Innate Immunity and Neuroinflammation

Scientists showed that multiple synthetically accessible bryologs replicate the anti-inflammatory effects of bryostatin-1 on innate immune cells in vitro, and a lead bryolog attenuates neuroinflammation in vivo.

Spatiotemporal Single-Cell Profiling Reveals That Invasive and Tissue-Resident Memory Donor CD8+ T Cells Drive Gastrointestinal Acute Graft-Versus-Host Disease

Scientists combined the serial intravascular staining technique with single-cell RNA sequencing to dissect the tightly connected processes by which donor T cells initially infiltrate tissues and then established a pathogenic tissue residency program in a rhesus macaque allo-HCT model that develops acute graft-versus-host disease.

Substrate-Specific Recognition of IKKs Mediated by USP16 Facilitates Autoimmune Inflammation

Investigators found that IKKβ ubiquitination on lysine-238 was substantially increased during inflammation. Using mass spectrometry, they identified USP16 as an essential regulator of the IKKβ ubiquitination level that selectively affected p105 phosphorylation without directly affecting p65 or IκBα phosphorylation.

Early-Life EV-A71 Infection Augments Allergen-Induced Airway Inflammation in Asthma through Trained Macrophage Immunity

Bone marrow-derived macrophages from recovered EV-A71-infected mice showed sustained innate immune memory that could drive naïve T helper cells toward Th2 and Th17 cell differentiation when in contact with mites.

FYN–TRAF3IP2 Induces NF-κB Signaling-Driven Peripheral T-Cell Lymphoma

Consistent with a driver oncogenic role, FYN–TRAF3IP2 expression in hematopoietic progenitors induced NF-κB-driven T-cell transformation in mice and cooperated with loss of the Tet2 tumor suppressor in peripheral T-cell lymphoma development.

Enoxacin Upregulates microRNA Biogenesis and Downregulates Cytotoxic CD8 T Cell Function in Autoimmune Cholangitis

Scientists showed that liver‐infiltrating dnTGFβRII CD8 T cells have significantly decreased levels of the miRNA biogenesis molecules P4ha1 and Ago2 along with significantly increased levels of granzyme B and perforin.
