Immune response to phosphorylcholine
Cellular Immunology, 1978Abstract Homologous and isologous anti-idiotypic antibodies against the PC-binding BALB/c myeloma protein HOPC-8 were raised in A/He and BALB/c mice, respectively. Isologous and homologous anti-HOPC-8 serum suppressed the response to PC in vitro specifically. The antibodies were purified by using HOPC-8 immunoabsorbent.

Phosphorylcholine antibodies in pulmonary infection
Medical Microbiology and Immunology, 1990Phosphorylcholine (PC) antibodies in serum from patients with pulmonary infection, and from normal individuals, were studied. Anti-PC antibodies were detectable in the serum from normal individuals at mean concentrations of 320 micrograms/ml for the IgG class and 110 micrograms/ml for the IgM class.

Preparation of phosphorylcholine-conjugated antigens
Journal of Immunological Methods, 1986In response to the need for a phosphorylcholine (PC) hapten that could be attached easily to carrier molecules, synthesis of PC-carrier conjugates was undertaken. An isothiocyanate-PC derivative was prepared by mixing p-aminophenyl-PC with thiophosgene.

1. Phosphorylcholine has been synthesised from choline chloride and phosphorus pentoxide and isolated as the double salt OCH2.CH2.N(CH3)3+ 2AgNO3.AgO—P—O‐O2. Phosphorylcholine, unlike most of the choline esters, is very stable towards alkaline and acid hydrolytic agents; this stability is attributed to the betaine structure of the compound.3 ...

Phosphorylcholine-Based Zwitterionic Biocompatible Thermogel
Biomacromolecules, 2015Zwitterionic polymers have been investigated as surface-coating materials due to their low protein adsorption properties, which reduce immunogenicity, biofouling, and bacterial adsorption of coated materials. Most zwitterionic polymers, reported so far, are based on (meth)acrylate polymers which can induce toxicity by residual monomers or amines ...

The preparation of an affinity sorbent containing immobilized L-glyceryl phosphorylcholine for affinity chromatography of phosphorylcholine-binding proteins from seminal plasma is described. The ligand was coupled either after its maleinylation to poly(acrylamide-allyl amine) copolymer or directly to divinyl sulfone-activated Sepharose.

Parasite Immunology, 2002
SUMMARY Immunomodulatory properties of phosphorylcholine (PC)‐containing glycosphingolipids from Ascaris suum were investigated utilizing immune cells from BALB/c mice. Proliferation of splenic B cells induced either via F(ab′)2 fragments of anti‐murine Ig (anti‐Ig) or LPS was significantly reduced when the glycosphingolipids were present in the ...

A Review on Phosphorylcholine-Coated Stents
Journal of Long-Term Effects of Medical Implants, 2017Stainless steel stents have been developed to perform their primary purpose of providing sufficient physical support to an artery following percutaneous transluminal coronary angioplasty (PTCA) in order to prevent vessel recoil. Early clinical problems, largely caused by subacute thrombosis (SAT), have been significantly reduced with a new generation ...

Crosslinkable coatings from phosphorylcholine-based polymers
Biomaterials, 20012-Methacryloyloxyethyl phosphorylcholine (MPC) was synthesised and then used in the preparation of crosslinked polymer membranes with lauryl methacrylate, hydroxypropyl methacrylate and trimethoxysilylpropyl methacrylate (crosslinker) comonomers. Some physical aspects of the membrane properties were evaluated in order to establish the basis for the ...

Of the several types of antibodies described in autoimmune disorders, the anti-phospholipid antibodies have received relatively little attention. These antibodies occur frequently in the sera of patients with a variety of autoimmune diseases, including systemic lupus erythematosus and related connective tissue disorders1.
