No significant difference was found between ODD-AION and NODD-AION eyes in terms of Snellen BCVA or perimetric mean deviation. On EDI-OCT, 28% of eyes with NODD-AION had peripapillary hyperreflective ovoid mass-like structures (PHOMS) and 7% had hyperreflective lines while 54% with ODD-AION had PHOMS and 66% had hyperreflective lines (P=0.006 and P less then 0.001, respectively). CONCLUSIONS The majority of our young NA-AION patients had ODD. This indicates that ODD may be an independent risk factor for the development of NA-AION, at least in younger patients. We suggest ODD-AION be recognized as a novel diagnosis. PURPOSE To use optical coherence tomography (OCT) to 3D characterize optic nerve head (ONH) peripapillary scleral bowing in non-highly myopic healthy eyes. DESIGN Cross-sectional, multicenter study. METHODS 362 non-highly myopic (+6 diopters (D) > spherical equivalent > -6D) eyes of 362 healthy subjects aging from 20-90 years underwent OCT ONH radial B-scan imaging. Bruch's membrane (BM), BM opening (BMO), ASCO and the peripapillary scleral surface were segmented. BMO and ASCO planes were fit and their centroids, major axes, ovality, area and offset were determined. Peripapillary scleral bowing was characterized by two parameters peripapillary scleral slope (ppSS) of three anterior peripapillary scleral segments (0-300, 300-700 and 700-1000 μm from the ASCO centroid); and ASCO depth relative to a peripapillary scleral reference plane (ASCOD-ppScleral). Peripapillary choroidal thickness (ppCT) was calculated relative to the ASCO as the minimum distance between the anterior scleral surface and BM. RESULTS ppSS and ASCOD-ppScleral both ranged from slightly inward through profoundly outward in direction. Both parameters increased with age and were independently associated with decreased ppCT. CONCLUSIONS In non-highly myopic healthy eyes outward peripapillary scleral bowing achieved substantial levels, was markedly increased with age and was independently associated with decreased peripapillary choroidal thickness. Our findings provide a normative foundation for characterizing this anatomy in high myopia and glaucoma and in eyes with optic disc tilt, torsion and peripapillary atrophy. Caspases regulate cell death, immune responses, and homeostasis. Caspase-6 is categorized as an executioner caspase but shows key differences from the other executioners. Overall, little is known about the functions of caspase-6 in biological processes apart from apoptosis. Here, we show that caspase-6 mediates innate immunity and inflammasome activation. Furthermore, we demonstrate that caspase-6 promotes the activation of programmed cell death pathways including pyroptosis, apoptosis, and necroptosis (PANoptosis) and plays an essential role in host defense against influenza A virus (IAV) infection. In addition, caspase-6 promoted the differentiation of alternatively activated macrophages (AAMs). Caspase-6 facilitated the RIP homotypic interaction motif (RHIM)-dependent binding of RIPK3 to ZBP1 via its interaction with RIPK3. Altogether, our findings reveal a vital role for caspase-6 in facilitating ZBP1-mediated inflammasome activation, cell death, and host defense during IAV infection, opening additional avenues for treatment of infectious and autoinflammatory diseases and cancer. Chronic obstructive pulmonary disease (COPD) is a progressive condition of chronic bronchitis, small airway obstruction, and emphysema that represents a leading cause of death worldwide. While inflammation, fibrosis, mucus hypersecretion, and metaplastic epithelial lesions are hallmarks of this disease, their origins and dependent relationships remain unclear. Here we apply single-cell cloning technologies to lung tissue of patients with and without COPD. Unlike control lungs, which were dominated by normal distal airway progenitor cells, COPD lungs were inundated by three variant progenitors epigenetically committed to distinct metaplastic lesions. When transplanted to immunodeficient mice, these variant clones induced pathology akin to the mucous and squamous metaplasia, neutrophilic inflammation, and fibrosis seen in COPD. Remarkably, similar variants pre-exist as minor constituents of control and fetal lung and conceivably act in normal processes of immune surveillance. However, these same variants likely catalyze the pathologic and progressive features of COPD when expanded to high numbers. Increasing evidence suggests that tRNA levels are dynamically and specifically regulated in response to internal and external cues to modulate the cellular translational program. However, the molecular players and the mechanisms regulating the gene-specific expression of tRNAs are still unknown. Using an inducible auxin-degron system to rapidly deplete RPB1 (the largest subunit of RNA Pol II) in living cells, we identified Pol II as a direct gene-specific regulator of tRNA transcription. Our data suggest that Pol II transcription robustly interferes with Pol III function at specific tRNA genes. This activity was further found to be essential for MAF1-mediated repression of a large set of tRNA genes during serum starvation, indicating that repression of tRNA genes by Pol II is dynamically regulated. selleck chemical Hence, Pol II plays a direct and central role in the gene-specific regulation of tRNA expression. Lymphocyte homeostasis and immune surveillance require that T and B cells continuously recirculate between secondary lymphoid organs. Here, we used intravital microscopy to define lymphocyte trafficking routes within the spleen, an environment of open blood circulation and shear forces unlike other lymphoid organs. Upon release from arterioles into the red pulp sinuses, T cells latched onto perivascular stromal cells in a manner that was independent of the chemokine receptor CCR7 but sensitive to Gi protein-coupled receptor inhibitors. This latching sheltered T cells from blood flow and enabled unidirectional migration to the bridging channels and then to T zones, entry into which required CCR7. Inflammatory responses modified the chemotactic cues along the perivascular homing paths, leading to rapid block of entry. Our findings reveal a role for vascular structures in lymphocyte recirculation through the spleen, indicating the existence of separate entry and exit routes and that of a checkpoint located at the gate to the T zone.
