Immunoglobulin G Fc Fragment‐Binding Proteins in Mycoplasma salivarium Cells [PDF]

Microbiology and Immunology, 1992
AbstractCell proteins of Mycoplasma salivarium were separated by sodium dodecyl sulfate‐polyacrylamide gel electrophoresis, transferred to membranes, then examined for reactivity with human IgG molecules, the Fc fragment of human IgG, and concanavalin A (ConA). Multiple protein bands bound IgG, and most of them also bound ConA.

The enhancement of the human immunoglobulin G Fc fragment-binding activity ofMycoplasma salivariumcells by trypsin treatment is ascribed to the binding of trypsin to the Fc fragment [PDF]

FEMS Microbiology Letters, 1995
Human immunoglobulin G Fc fragment-binding activity of Mycoplasma salivarium cells was remarkably enhanced by trypsin treatment of the cells. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis profile of proteins of the cells treated with trypsin was the same as that of the cells treated with pronase, although pronase treatment had been shown to

Bacterial Proteins and Their Proposed Interactions with Fc or Fab Fragments of Immunoglobulins

Biochemistry & Physiology: Open Access, 2014
The reactivity of Immunoglobulin Binding Proteins (IBP) to Fc and/or Fab fragments of immunoglobulins was summarized in this review. Staphylococcal protein A (SpA), Streptococcal protein G and Peptostreptococcal protein L (SpL) were the IBP reported. SpA reacted with IgG from skunk, coyote, raccoon, mule and donkey.

In vivo secretion of the mouse immunoglobulin G Fc fragment from rat submandibular glands [PDF]

The Journal of Gene Medicine, 2009
AbstractBackgroundSalivary glands have been proposed as target organs for gene therapy. They secrete endogenous, as well as transgenic proteins, in a polarized manner. Transgene‐encoded regulated pathway proteins primarily follow the regulated pathway in rat salivary glands and are secreted into saliva in an exocrine manner.

Effect of IgG fragments in IVIG(pH4)on phagocytosis of sensitized erythrocytes by macrophage

Zhongguo shuxue zazhi, 2022
Objective To research the effect of the Fc, Fab and F(ab′)2 fragments of immunoglobulin G, the main components of Human Immunoglobulin(pH4) for Intravenous Injection(IVIG), on the phagocytic function of macrophages derived from THP-1 cells. Methods First

The Dual Targeting of FcRn and FcγRs via Monomeric Fc Fragments Results in Strong Inhibition of IgG-Dependent Autoimmune Pathologies

Frontiers in Immunology, 2021
Novel molecules that directly target the neonatal Fc receptor (FcRn) and/or Fc gamma receptors (FcγRs) are emerging as promising treatments for immunoglobulin G (IgG)-dependent autoimmune pathologies.

Production of IgG1-based bispecific antibody without extra cysteine residue via intein-mediated protein trans-splicing

Scientific Reports, 2021
A major class of bispecific antibodies (BsAbs) utilizes heterodimeric Fc to produce the native immunoglobulin G (IgG) structure. Because appropriate pairing of heavy and light chains is required, the design of BsAbs produced through recombination or ...

Collagen Fragments Produced in Cancer Mediate T Cell Suppression Through Leukocyte-Associated Immunoglobulin-Like Receptor 1

Frontiers in Immunology, 2021
The tumor microenvironment (TME) is a complex structure comprised of tumor, immune and stromal cells, vasculature, and extracellular matrix (ECM). During tumor development, ECM homeostasis is dysregulated. Collagen remodeling by matrix metalloproteinases

The herpes virus Fc receptor gE-gI mediates antibody bipolar bridging to clear viral antigens from the cell surface. [PDF]

PLoS Pathogens, 2014
The Herpes Simplex Virus 1 (HSV-1) glycoprotein gE-gI is a transmembrane Fc receptor found on the surface of infected cells and virions that binds human immunoglobulin G (hIgG).
