Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Spatiotemporal segregation of human marginal zone and memory B cell populations in lymphoid tissue

Nature Communications, 2018
Human memory and marginal zone B cells share some features including CD27 expression and somatic hypermutation, but their lineage relationship is still unclear.

Secondary Mechanisms of Affinity Maturation in the Human Antibody Repertoire

Frontiers in Immunology, 2013
V(D)J recombination and somatic hypermutation (SHM) are the primary mechanisms for diversification of the human antibody repertoire. These mechanisms allow for rapid humoral immune responses to a wide range of pathogenic challenges.

Multiomics Insights Into AL Amyloidosis

Medicine Bulletin, EarlyView.
ABSTRACT Light chain amyloidosis is a systemic or localized protein conformational disorder triggered by misfolded immunoglobulin light chains, leading to amyloid fibril deposition. The disease is characterized by multiorgan involvement and delayed diagnosis, contributing to poor prognosis and high mortality rates.

Nanobodies as next‐generation targeting platforms: From discovery technologies to translational biomedicine

VIEW, EarlyView.
Nanobodies, derived from the variable domains of camelid heavy‐chain‐only antibodies, have emerged as transformative biomedical tools due to their nanoscale size, exceptional stability, and unique capacity to recognize cryptic epitopes. This review provides a comprehensive overview of the field, outlining the structural and biochemical features of ...

Recurrent Somatic Structural Variations Contribute to Tumorigenesis in Pediatric Osteosarcoma

Cell Reports, 2014
Pediatric osteosarcoma is characterized by multiple somatic chromosomal lesions, including structural variations (SVs) and copy number alterations (CNAs).

Autosomal Dominant Hyper‐IgE Syndrome Patients Retain IL10‐Producing preTh17‐Cells That Are Activated by Opportunistic Pathogens and Support IgE Production

Allergy, EarlyView.
IL‐10 producing CCR6+Th‐cells are central memory T‐cells that express ROR‐γt and differentiate to Th17‐cells via an autocrine loop of STAT3‐activating cytokines (preTh17). STAT3‐deficient AD‐HIES patients lack Th17‐ and Tfh17‐cells but retain preTh17‐ and Th1/17‐cells.

Increased anergic B cells and decreased antibody‐secreting cells during romiplostim treatment in patients with immune thrombocytopenia

British Journal of Haematology, EarlyView.
Summary Patients with immune thrombocytopenia (ITP) exhibit substantial heterogeneity in treatment responses. Approximately 30%–50% of patients maintain remission after discontinuation of thrombopoietin receptor agonists (TPO‐RA), suggesting immunomodulatory effects beyond enhanced thrombopoiesis.

Teleost IgD+IgM− B Cells Mount Clonally Expanded and Mildly Mutated Intestinal IgD Responses in the Absence of Lymphoid Follicles

Cell Reports, 2019
Summary: Immunoglobulin D (IgD) is an ancient antibody with dual membrane-bound and fluid-phase antigen receptor functions. The biology of secreted IgD remains elusive. Here, we demonstrate that teleost IgD+IgM− plasmablasts constitute a major lymphocyte

Pleiotropic Roles of FBXO11 in Tumorigenesis: Implications for Targeted Therapy

Cancer Science, EarlyView.
This complex comprises of scaffold CUL1, SKP1, RBX1 and FBXO11 receptor. The substrate is phosphorylated by specific kinase enzyme and recognized by the substrate recognition domain. FBXO11 targets numerous substrates for ubiquitination and degradation, FBXO11 substrates mainly include Snail, ZEB1, p53, BCL6, CDT2, CIITA, Cdc25a, hnRNPA2B1, SAMD1 and ...
