Gut Mycobiota‐Associated Tryptophan Catabolites Protect Against Metabolic Dysfunction‐Associated Steatotic Liver Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Accumulating evidence suggests that the intestinal microbiota participates in the progression of metabolic dysfunction‐associated steatotic liver disease (MASLD) through microbiota‐host interaction. However, the beneficial role of commensal mycobiota in MASLD progression remains poorly understood.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Functional immunoglobulin transgenes guide ordered B-cell differentiation in Rag-1-deficient mice [PDF]

open access: yes, 1994
We have examined the regulatory role of the individual components of the immunoglobulin antigen receptor in B-cell development by transgenic complementation of Rag-1 deficient (Rag-1⁻) mice. Complementation with a membrane µ heavy chain (µHC) gene allows

Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

open access: yesAdvanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

B lymphocyte-specific protein binding near an immunoglobulin kappa-chain gene J segment. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1987
Nuclear extracts from pre-B and B cell lines contain a nuclear DNA binding protein (kappa locus protein, KLP) that specifically recognizes a DNA sequence in the immunoglobulin kappa light chain joining (J) segment gene region. KLP is not observed in mature B cells, T cells, or nonlymphoid cell types.

Evidence for somatic selection of natural autoantibodies. [PDF]

open access: yes, 1992
Natural autoantibodies are primarily immunoglobulin M (IgM) antibodies that bind to a variety of self-antigens, including self-IgG. Accounting for a large proportion of the early B cell repertoire, such polyspecific autoantibodies are speculated to ...

Post CAR‐T Measurable Residual Disease Monitoring in Mantle Cell Lymphoma Enables Early Detection of Disease Relapse

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT CD19‐directed chimeric antigen receptor (CAR) T‐cell therapy has transformed outcomes for patients with relapsed or refractory (r/r) mantle cell lymphoma (MCL), yet more than 40% relapse within one year. Early identification of patients at risk for progression could inform post CAR‐T surveillance and consolidation strategies.

Sequence diversity within a subgroup of mouse immunoglobulin kappa chains controlled by the IgK-Ef2 locus. [PDF]

open access: yesThe Journal of experimental medicine, 1981
We previously showed that a chromosome 6 locus, IgK-Ef2, controls a pair of prominent bands in normal mouse light-chain isoelectric focusing profiles. Screening of myeloma light chains derived from BALB/c mice (an IgK-EF2 alpha strain) led to the identification of seven light chains cofocusing with the polymorphic bands controlled by IgK-Ef2.

Astrocytes express aberrant immunoglobulins as putative gatekeeper of astrocytes to neuronal progenitor conversion

open access: yesCell Death and Disease, 2023
Using multi-omics analyses including RNAseq, RT-PCR, RACE-PCR, and shotgun proteomic with enrichment strategies, we demonstrated that newborn rat astrocytes produce neural immunoglobulin constant and variable heavy chains as well as light chains. However,

Recent duplication and germ-line diversification of rat immunoglobulin kappa chain gene joining segments. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1982
Sequence determination of the joining segment gene (J) cluster in the kappa chain (J kappa) in the embryonic context demonstrates that rat genome contains seven J kappa gene segments that expanded from an ancestral cluster of five J kappa genes. The rat J segments are separated by about 300 base pairs (bp) and are flanked 5' by the presumed variable ...
