Gene Expression of Promyelocytic Leukemia Proteins and IFN-γ Is Reduced in Rotavirus-Infected Children

Background: Rotavirus infection is one of the most common gastroenteritis in the world, and a million cases are registered to enter hospital every year. Promyelocytic leukemia proteins (PMLs) are IFN-up-regulated proteins, and one of their critical functions is working as antiviral proteins. Recently, promyelocytic leukemia isoform II (PML-II) has been depicted as an isoform responsible for the...

The Role of Bacterial Vectors in the Expression of Human IFN-y Gene

Interplay among coactivator-associated arginine methyltransferase 1, CBP, and CIITA in IFN-gamma-inducible MHC-II gene expression.

Class II major histocompatibility (MHC-II) genes are prototype targets of IFN-gamma. IFN-gamma activates the expression of the non-DNA-binding master regulator of MHC-II, class II transactivator (CIITA), which is crucial for enhanceosome formation and gene activation. This report shows the importance of the histone methyltransferase, coactivator-associated arginine methyltransferase (CARM1/PRMT...

The role of IFN-γ in regulation of IFN-γ-inducible protein 10 (IP-10) expression in lung epithelial cell and peripheral blood mononuclear cell co-cultures

BACKGROUND Interferons play a critical role in regulating both the innate and adaptive immune responses. Previous reports have shown increased levels of IFN-gamma, IFN-gamma-inducing IL-12 and IFN-gamma-inducible chemokine IP-10 in patients with chronic obstructive pulmonary disease (COPD). METHODS The present study focuses on the regulation of the IP-10 secretion in co-cultures of lung epith...

A novel mechanism for the regulation of IFN-γ inducible protein-10 expression in rheumatoid arthritis

Chemokines play an essential role in the progression of rheumatoid arthritis (RA). In the present study we examined the expression and regulatory mechanisms of IFN-gamma inducible protein (IP)-10 in RA synovitis. RA synovial fluid contained greater amounts of IP-10 than did synovial fluid from patients with osteoarthritis. Immunolocalization analysis indicated that IP-10 was associated mainly w...
