Nonstochastic pairing of immunoglobulin heavy and light chains expressed by chronic lymphocytic leukemia B cells is predicated on the heavy chain CDR3.

Blood, 2005
We analyzed the immunoglobulin (Ig) variable heavy (IGHV) and variable light chain genes used by leukemia cells of 258 unrelated patients with chronic lymphocytic leukemia (CLL) found to express unmutated Ig heavy chains (IgH) encoded by a 51p1 allele of

QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

Virtual reality based approach to protein heavy-atom structure reconstruction [PDF]

arXiv, 2014
A commonly recurring problem in structural protein studies, is the determination of all heavy atom positions from the knowledge of the central alpha-carbon coordinates. We employ advances in virtual reality to address the problem. The outcome is a 3D visualisation based technique where all the heavy backbone and side chain atoms are treated on equal ...

Population Genetics of the Heavy Chain Immunoglobulin Allotypes in the Rabbit

Experimental Biology and Medicine, 1972
Synthesis of the heavy immunoglobulin chain is controlled by two genes, one being in control of the variable, the second in control of the constant portion of the chain (1-3). Elucidation of the relation between the genes for constant and variable portions of the heavy chain and of the mechanism of assembly are crucial for an analysis of the generation

Mechanical Load‐Induced Upregulation of Talin2 through Non‐Canonical Deubiquitination of OTUB1 Drives Facet Joint Osteoarthritis Pathogenesis

Advanced Science, EarlyView.
Facet joint osteoarthritis (FJOA), prevalent in the elderly, involves Talin2 upregulation promoting ECM degradation while suppressing synthesis. Mechanical load stabilizes Talin2 via OTUB1‐mediated non‐canonical deubiquitination, driving CCL2 expression that recruits immune cells, exacerbating inflammatory joint degeneration.

Individual B cells transcribe multiple rearranged immunoglobulin light chains in teleost fish

iScience, 2021
Summary: B cells express a unique antibody protein which comprises two pairs of immunoglobulin (Ig) heavy (H) and light (L) chains. In addition to an invariable constant (C) region, IgH and IgL chains encompass a variable (V) region mediating antigen ...

Intrachain disulphide bridges in immunoglobulin G heavy chains. The Fc fragment.

Biochemical Journal, 1968
The disulphide bridges of the Fc fragment (C-terminal half of the heavy chain) have been studied in several human immunoglobulins, containing heavy chains of different antigenic types (gamma1, gamma2, gamma3 and gamma4), and in heavy-chain-disease ...

Sortilin‐Mediated Rapid, Precise and Sustained Degradation of Membrane Proteins via mRNA‐Encoded Lysosome‐Targeting Chimera

Advanced Science, EarlyView.
The study identified sortilin as a promising LTR, enabling targeted degradation of oncogenic proteins through an mRNA‐encoded MedTAC strategy. In a mouse model, MedTACPTK7 reduced PTK7 by up to 80%, extended survival, and showed excellent pharmacokinetics without toxicity, providing a scalable platform for targeted therapies.

Diversity and structure of human T-Cell receptor β-chain variable region genes [PDF]

, 1986
The nucleotide sequences of 27 T-cell receptor β cDNA clones isolated from a human peripheral lymphocyte library were determined and compared to five additional published sequences. These cDNA clones represent 22 distinct T-cell receptor β-chain variable

Emergence of clonal selection and affinity maturation in an ab initio microscopic model of immunity [PDF]

arXiv, 2007
Mechanisms of immunity, and of the host-pathogen interactions in general are among the most fundamental problems of medicine, ecology, and evolution studies. Here, we present a microscopic, protein-level, sequence-based model of immune system, with explicitly defined interactions between host and pathogen proteins..
