rs4251545 of IRAK4 (p.Ala428Thr) modified the susceptibility to HBV-related HCC via increased proliferation rate and reduced production of inflammatory cytokines and chemokines
-
synthetic routes with moderate to high yields have been developed to produce the reference standard 9, demethylated precursor 8 and target tracer [11C]9. The radiosynthesis employed [11C]CH3OTf for N-[11C]methylation at the piperazin position of the desmethyl precursor, followed by product purification and isolation using a semi-preparative RP HPLC combined with SPE. [11C]9 was obtained in high radiochemical yield, radioc

The high mRNA levels of IRAK1 and IRAK4 were correlated with the development of Behcet's disease, which suggested that IRAK1 and IRAK4 might participate in the pathogenesis of Behcet's disease
-
IRAK-4 Arg12 is also essential for Myddosome assembly and signalling and we propose that phosphorylated Ser8 induces the N-terminal loop to fold into an alpha-helix. This conformer is stabilised by an electrostatic interaction between phospho-Ser8 and Arg12 and would destabilise a critical interface between IRAK-4 and MyD88.
-
Our data established IRAK4 as a novel therapeutic target for PDAC treatment. Development of potent IRAK4 inhibitors is needed for clinical testing.
-
Data suggest that IRAK4 activity regulates activation of IRF5, TAK1, and IKKB in monocytes; IRAK4 activation of TAK1-IKKB-IRF5 axis leads to induction of cytokines and interferons following TLR7/TLR8 stimulation. (IRAK4 = interleukin-1 receptor-associated kinase 4; IRF5 = interferon regulatory factor-5; TAK1 = MAPK kinase kinase 7; IKKB = I-kappa B kinase; TLR = toll-like receptor)

AMPK activation inhibited IL-1beta-stimulated CXCL10 secretion, associated with reduced interleukin-1 receptor associated kinase-4 (IRAK4) phosphorylation.
-
By CRISPR/Cas9-induced inactivation of TLR9, MyD88, IRAK4 and IRAK1 we confirm that BZLF1 repression is dependent on functional TLR9 and MyD88 signaling, and identify IRAK4 as an essential element for TLR9-induced repression of BZLF1 expression upon BCR cross-linking
-
the polymorphisms in TLR-MyD88-NF-kappaB signaling pathway confer genetic susceptibility to Type 2 diabetes mellitus and diabetic nephropathy.
-
data show that in pericytes, MyD88 and IRAK4 are key regulators of 2 major injury responses: inflammatory and fibrogenic.
-
Data suggest that, in monocytes and macrophages, the interleukin-1B- (IL1B)-stimulated trans-autophosphorylation of IRAK4 is initiated by MYD88- (myeloid differentiation primary response gene 88)-induced dimerization of IRAK4. In contrast, IRAK1 (interleukin-1 receptor-associated kinase 1) is inactive in unstimulated monocytes/macrophages and is converted to an active protein kinase in response to IL1B.

IRAK4 - Gene involved in innate immunity that have been associated with Chronic Rhinosinusitis.
-
The estimated prevalence of IRAK4 gene polymorphism found in a Portuguese Caucasian population was 26.8 % (CI 95%) [20.1, 34.7 %]. A model to predict the inflammatory response in the maxillary sinus in the presence etiological factors of dental origin was constructed.

missense mutation results in immunological deficiency phenotype

Siblings with compound heterozygosity for two mutations: a frameshift mutation at one allele (c.1146delT (p.G383fs)), and an in-frame duplication variant at the other (c.255_260dup6 (p.D86_L87dup)) leading to fatal pneumococcal meningitis is described.
-
This is the first study to show an association between single nucleotide polymorphisms in IRAK1, IRAK4 and MyD88, and the presence of severe invasive pneumococcal disease.
-
Src, Syk, IRAK1, and IRAK4 have roles in anti-inflammatory responses mediated by dietary flavonoid Kaempferol
-
findings suggest that rare, functional variants in MYD88, IRAK4 or IKBKG do not significantly contribute to IPD susceptibility in adults at the population level
-
High mRNA levels of IRAK1 and IRAK4 correlated with VKH disease activity.
-
Studies indicate that interleukin-1 receptor-associated kinase 4 protein (IRAK4), a serine/threonine kinase, plays a key role in both inflammation and oncology diseases.
