Objective We employed global genetic deletion of CD14 and intra‐articular CD14 blockade across multiple murine osteoarthritis (OA) models that vary in severity of pathology and rate of progression to test the hypothesis that CD14 inhibition attenuates synovial inflammation and associated pain during disease progression.

Protein tyrosine kinases in the initiation of antigen receptor signaling
Current Opinion in Immunology, 1995Intracellular responses to antigen receptor engagement involve the activation of protein tyrosine kinases and the tyrosine phosphorylation of cellular proteins, including components of the antigen receptor. Phosphorylation of two tyrosine residues within an 18 amino acid segment of the cytoplasmic domain of antigen receptor subunits, and the subsequent

Regulation of antigen receptor signal transduction by protein tyrosine kinases
Current Opinion in Immunology, 1996The past two years have seen further clarification of the early events occurring in antigen receptor signal transduction that are mediated by the immunoreceptor tyrosine-based activation motif (ITAM). The ITAM was shown to be a specific binding site for the ZAP-70/Syk protein tyrosine kinases and the structure of this complex was solved.

Signalling pathways initiated by receptor protein tyrosine kinases in Drosophila
Current Opinion in Cell Biology, 1994The isolation and characterization of Drosophila mutations in receptor protein tyrosine kinases (RPTKs) have allowed a detailed analysis of the cellular processes regulated by these proteins. Recent investigations have identified a number of putative ligands involved in the activation of the receptors, and have demonstrated that these RPTKs trigger an ...

Membrane receptors with protein-tyrosine kinase activity
Biochimie, 1987Protein-tyrosine kinase activities have appeared so far to be intrinsic for two classes of proteins: the transforming proteins of certain retroviral oncogenes and the membrane receptors for certain cellular growth factors. In this latter family, the protein-tyrosine kinase is activated upon binding of the growth factor to its receptor and ...

src-related protein tyrosine kinases and their surface receptors
Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, 1993The CD4-p56lck and CD8-p56lck complexes have served as a paradym for an expanding number of interactions between src-family members (p56lck, p59fyn, p56lyn, p55blk) and surface receptors. These interactions implicate src-related kinases in the regulation of a variety of intracellular events, from lymphokine production and cytotoxicity to the expression

Non-receptor protein tyrosine kinases
Frontiers in Bioscience, 2003The protein tyrosine kinases (PTKs) are enzymes catalyzing the transfer of the gamma-phosphate group of ATP to the hydroxyl groups of specific tyrosine residues in peptides. Although phosphotransfer reactions catalyzed by various PTKs are similar with regard to their basic mechanisms, their biological functions demonstrate a considerable degree of ...

B61 is a ligand for the ECK receptor protein-tyrosine kinase
Nature, 1994A protein ligand for the ECK receptor protein-tyrosine kinase has been isolated by using the extracellular domain (ECK-X) of the receptor as an affinity reagent. Initially, concentrated cell culture supernatants were screened for receptor binding activity using immobilized ECK-X in a surface plasmon resonance detection system.

Comparative characterization of receptor and non-receptor associated protein tyrosine kinases
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1989By using poly(Glu: Tyr, 4:1) as an exogenous substrate, the characteristics of insulin receptor associated protein tyrosine kinase (PTK) from rabbit skeletal muscle has been compared with a growth factor-independent non-receptor PTK partially purified from rat lung particulate fraction.
