Mapping the vascular organization of the brain is of great importance across various domains of basic neuroimaging research, diagnostic radiology, and neurology. However, the intricate task of precisely mapping vasculature across brain regions and cortical layers presents formidable challenges, resulting in a limited understanding of neurometabolic factors influencing the brain's microvasculature. Addressing this gap, our study investigates whole-brain vascular volume using ferumoxytol-weighted laminar-resolution multi-echo gradient-echo imaging in macaque monkeys. We validate the results with published data for vascular densities and compare them with cytoarchitecture, neuron and synaptic densities. The ferumoxytol-induced change in transverse relaxation rate (ΔR

Understanding developmental changes in neuronal lineages is crucial to elucidate how they assemble into functional neural networks. Studies investigating nervous system development in model systems have only focused on select regions of the CNS due to the limited availability of genetic drivers that target specific neuronal lineages throughout development and adult life. This has hindered our understanding of how distinct neuronal lineages interconnect to form neuronal circuits during development. Here, we present a split-GAL4 library composed of genetic driver lines, which we generated via editing the genomic locus of lineage-specific transcription factors and demonstrate that we can use this library …

Impact Of Vein-To-Vein Time In Patients With R/R Lbcl Treated With Axicabtagene Ciloleucel, Frederick L Locke, Armin Ghobadi, Et Al.

2020-Current year OA Pubs

Chimeric antigen receptor (CAR) T-cell products axicabtagene ciloleucel (axi-cel), tisagenlecleucel (tisa-cel), and lisocabtagene maraleucel (liso-cel) are approved for relapsed/refractory (R/R) large B-cell lymphoma (LBCL). Emerging evidence indicates that delayed CAR T-cell infusion, including prolonged time from leukapheresis to infusion, known as vein-to-vein time (V2Vt), may adversely impact clinical outcomes. We conducted a systematic literature review (SLR) and meta-analysis to identify differences in V2Vt in patients with R/R LBCL treated with axi-cel, tisa-cel, or liso-cel. The impact of V2Vt (< 28 days vs ≥28 to < 40 days vs ≥40 days) on effectiveness and safety outcomes was evaluated in patients treated with axi-cel enrolled in a post-authorization safety study using the Center for International Blood and Marrow Transplant Research data. SLR and meta-analysis showed that patients treated with axi-cel had the shortest median V2Vt (30.6 days) compared with tisa-cel (48.4 days) or liso-cel (35.9 days). Real-world analysis of patients treated with axi-cel demonstrated that V2Vt ≥40 days was associated with significantly lower complete response rate than V2Vt < 28 days (odds ratio [OR], 0.61) or ≥28 to < 40 days (OR, 0.66) and significantly worse overall survival than V2Vt < 28 days (hazard ratio [HR], 1.33) or ≥28 to < 40 days (HR, 1.36). Higher prolonged thrombocytopenia rates were observed in patients with axi-cel V2Vt ≥28 to < 40 days or ≥40 days compared with < 28 days (OR, 1.44 or 1.95, respectively). Together, these results show the impact of V2Vt on patient outcomes with axi-cel therapy and that earlier infusion with CD19-CAR therapies may be beneficial.

Insulin secretion from pancreatic β cells is initiated by membrane potential depolarization, followed by activation of voltage-gated Ca2+ channels to trigger Ca2+-mediated insulin vesicle fusion with the β cell plasma membrane. Here, we show that β cell swelling associated with glucose metabolism was sensed by LRRC8 channel complexes and contributed to insulin secretion. Hypertonic perfusate (360-380 mOsm) dose dependently impaired glucose-stimulated insulin secretion by counteracting β cell swelling. Hypotonic perfusate alone, independent of glucose stimulation or KATP channel closure, was sufficient to increase β cell intracellular Ca2+ and trigger insulin secretion. Inhibition of sodium-potassium-chloride cotransporter-1 with bumetanide, which diminished the …

The human kidney maintains homeostasis through a complex network of up to a million nephrons, its fundamental tissue units. Using innovative tissue processing and light sheet fluorescence microscopy, we mapped the 3D neurovascular connectivity of nephrons to understand how their structural organization enables coordinated functions like filtration, absorption, and blood pressure regulation. Our analysis revealed developmental changes in glomerular orientation, density, volume, and innervation from birth through aging. We discovered an extensive nerve network connecting different nephron segments and organizing glomeruli into distinct communities. These communities are linked through "mother glomeruli" that serve as control centers, creating a repeating pattern …

Innate Lymphoid Cells In Inflammatory Bowel Disease, Xin Yao, Kaiming Ma, Yangzhuangzhuang Zhu, Siyan Cao

2020-Current year OA Pubs

Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is a chronic inflammatory disorder of the gastrointestinal tract with rising incidence and an unclear etiology. Innate lymphoid cells (ILCs) have recently emerged as key regulators of mucosal immunity and tissue homeostasis and are increasingly implicated in IBD. Unlike adaptive lymphocytes, ILCs do not require antigen recognition and clonal expansion to respond rapidly to environmental cues and shape immune responses. In a healthy gut, ILCs maintain intestinal homeostasis by guarding the epithelial barrier, protecting against pathogens, and mounting proper responses to external insults. However, their altered differentiation, proliferation, recruitment, activation, …

Several "primary atopic disorders" are linked to monogenic defects that attenuate TCR signaling, favoring T helper type 2 (TH2) cell differentiation. Patients with CARD11-associated atopy with dominant interference of NF-κB signaling (CADINS) disease suffer from severe atopy, caused by germline loss-of-function/dominant interfering (LOF/DI) CARD11 variants. The CARD11 scaffold enables TCR-induced activation of NF-κB, mTORC1, and JNK signaling, yet the function of CARD11-dependent JNK signaling in T cells remains nebulous. Here we show that CARD11 is critical for TCR-induced activation of JNK1 and JNK2, as well as canonical JUN/FOS AP-1 family members. Patient-derived CARD11 DI variants attenuated WT CARD11 JNK signaling, …
