Gamma-globulin Inhibits Superantigen-induced Lymphocyte Proliferation and Cytokine Production

Allergology International, 2007
Background: High-dose pooled human immunoglobulin (PHIG) treatment is sometimes effective in superantigen related inflammatory diseases, such as toxic shock syndrome and Kawasaki disease.

IgG Fab Fragments Forming Bivalent Complexes by a Conformational Mechanism That Is Reversible by Osmolytes*

Journal of Biological Chemistry, 2012
Background: Isolated Fab fragments can spontaneously multimerize over time. Results: Distinct conformations are associated with monovalent Fabs versus those in bivalent complexes. Conclusion: Monovalency can be preserved upon conformational stabilization

Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.

Junctional Bradycardia as Early Sign of Digoxin Toxicity in a Premature Infant with Congestive Heart Failure due to a Left to Right Shunt

American Journal of Perinatology Reports, 2016
Introduction Congestive heart failure due to left to right cardiac shunt is usually managed medically with diuretics, angiotensin converting enzyme inhibitors, and, in some cases, with the addition of digoxin.

The structures of secretory and dimeric immunoglobulin A [PDF]

, 2020
Secretory (S) Immunoglobulin (Ig) A is the predominant mucosal antibody, which binds pathogens and commensal microbes. SIgA is a polymeric antibody, typically containing two copies of IgA that assemble with one joining-chain (JC) to form dimeric (d) IgA ...

Biochemical and structural characterization of the human gut microbiome metallopeptidase IgAse provides insight into its unique specificity for the Fab' region of IgA1 and IgA2.

PLoS Pathogens
Human immunoglobulin A (IgA), comprising the isotypes IgA1 and IgA2, protects ~400 m2 of mucosal surfaces against microbial infections but can also lead to aberrant IgA deposits that cause disease. Certain bacteria have evolved peptidases that cleave the

Staphylococcus pseudintermedius Sbi paralogs inhibit complement and bind IgM, IgG Fc and Fab.

PLoS ONE, 2019
The success of staphylococci as pathogens has been attributed, in part, to their ability to evade their hosts' immune systems. Although the proteins involved in evasion have been extensively studied in staphylococci affecting humans little ...

Expression of an anti-CD33 single-chain antibody by Pichia pastoris [PDF]

, 2005
CD33 is a cell surface glycoprotein expressed on cells of myelomonocytic lineage, leukaemic cells, but not haematopoietic stem cells. By virtue of its expression pattern, CD33 has become a popular target for new immunotherapeutic approaches to treat ...

Structural Basis for Trivalent Cross‐Linking of a Patient‐Derived IgE Antibody by the Major Peanut Allergen Ara h 2.0201

Allergy, EarlyView.
Graphical The crystal structure of a major peanut allergen Ara h 2.0201 in a complex with a human‐derived IgE Fab fragment has been determined. The immunocomplex shows the trivalent binding of Fabs, creating a cross‐linked structure effective in the formation of large complexes on the surface of effector cells. Hydroxylation of proline has implications

Proteomic profile of CSF obtained at the time of diagnosis determines amyotrophic lateral sclerosis progression and survival: CXCL7 levels in disease prognosis and survival

Brain Pathology, EarlyView.
Untargeted multiomic profiling of cerebrospinal fluid reveals that proteomic, but not lipidomic, signatures robustly distinguish ALS patients from controls and stratify individuals by survival, highlighting marked molecular differences between short survival and long survival disease.
