Preclinical Evaluation of an Engineered Single-Chain Fragment Variable-Fragment Crystallizable Targeting Human CD44

Human single-chain variable fragment that specifically targets arthritic cartilage

OBJECTIVE To demonstrate that posttranslational modification of type II collagen (CII) by reactive oxygen species (ROS), which are known to be present in inflamed arthritic joints, can give rise to epitopes specific to damaged cartilage in rheumatoid arthritis (RA) and osteoarthritis (OA) and to establish a proof of concept that antibodies specific to ROS-modified CII can be used to target ther...

RECOMBINANT SINGLE CHAIN VARIABLE FRAGMENT ANTIBODIES (scFv) AGAINST Pro144-Leu155 FRAGMENT OF HUMAN PROTEIN C.

The aim of this work was to obtain the recombinant single chain variable fragments of antibodies (scFv) against human protein C, the key component of blood anticoagulation system. For this purpose a peptide that mimics a Pro144-Leu155 sequence of protein C was synthesized and the murine immune scFv library against this peptide was constructed. The protein C specific scFv 9E were selected from t...

Identification of conformational epitopes on fragment crystallizable region of human Immunoglobulin G by immunoinformatic

Background: Immunoglobulins are a group of proteins have important role in defense against microorganisms. Human immunoglobulins are divided into five classes: IgA, IgM, IgD, IgE and IgG. Immunoglobulin G (IgG) is the highest abundant antibody in serum and extravascular fluids. The extent of serum IgG is related to severity of several diseases such as infections, so IgG has great diagnostic wor...

Single-Chain Fragment Variable Passive Immunotherapies for Neurodegenerative Diseases

Accumulation of misfolded proteins has been implicated in a variety of neurodegenerative diseases including prion diseases, Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). In the past decade, single-chain fragment variable (scFv) -based immunotherapies have been developed to target abnormal proteins or various forms of protein aggregates including Aβ, SNCA, Ht...
