Role of the Ccr4‐Not Complex in Histone Acetylation

The FASEB Journal, 2012
The Ccr4‐Not complex is a global regulator of gene expression that affects expression both positively and negatively. The complex, conserved from yeast to human, is composed of at least nine subunits. The Ccr4 subunit functions in the control of mRNA deadenylation and transcriptional initiation/elongation.

A CAF40-binding motif facilitates recruitment of the CCR4-NOT complex to mRNAs targeted by Drosophila Roquin

Nature Communications, 2017
Roquin proteins downregulate target mRNA expression by recruiting effectors such as the CCR4-NOT deadenylase complex. Here the authors provide molecular details of how Roquin proteins recruit the CCR4-NOT complex to repress the expression of its targets.

Diverging in Vivo Immune Response Patterns After Oral Food Challenge in Peanut Allergic Adults

Clinical &Experimental Allergy, EarlyView.
After the oral food challenge, peanut (PN)‐allergic adults were monitored over 4 weeks, which revealed diverging immune response patterns, with strong responders (SR) exhibiting heightened Ara h 2+ B cell expansion, PN sIgE induction and increasing PN‐specific Tconv. Weak responders (WR) had more activated PN‐specific Tregs.

Reconstitution of recombinant human CCR4-NOT reveals molecular insights into regulated deadenylation

Nature Communications, 2019
The CCR4-NOT complex shortens poly(A) tails of messenger RNAs. By biochemical reconstitution of the entire human CCR4-NOT complex, the authors show the stimulatory roles of non-enzymatic subunits and the importance of the interaction between CAF40 and ...

CCR4 Antagonist (C021) Administration Diminishes Hypersensitivity and Enhances the Analgesic Potency of Morphine and Buprenorphine in a Mouse Model of Neuropathic Pain

Frontiers in Immunology, 2020
Neuropathic pain is a chronic condition that remains a major clinical problem owing to high resistance to available therapy. Recent studies have indicated that chemokine signaling pathways are crucial in the development of painful neuropathy; however ...

AMSC‐sEVs Ameliorated Crohn's Disease by Inhibiting Macrophage‐Myofibroblast Transition Through the Delivery of MFGE8

Cell Proliferation, EarlyView.
Our study demonstrated that TGF‐β1 activated MAPK signalling pathway and promoted the MMT and secretion of CCL17 under CD‐associated intestinal inflammatory conditions. AMSC‐sEVs can deliver MFGE8, which inhibits MMT and CCL17‐mediated Treg recruitment by suppressing the MAPK signalling pathway, thereby alleviating intestinal fibrosis.

Deadenylation of mRNA by the CCR4-NOT complex in Drosophila: molecular and developmental aspects

Frontiers in Genetics, 2014
Controlled shortening of the poly(A) tail of mRNAs is the first step in eukaryotic mRNA decay and can also be used for translational inactivation of mRNAs.

Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

scRNA‐Seq reveals anti‐lymphoma immune responses in mogamulizumab‐associated skin eruptions

Journal of the European Academy of Dermatology and Venereology, EarlyView.
CCR4 was expressed in malignant clones and regulatory T cells in untreated CTCL, that were decreased in MAR. Malignant clones in MAR showed a silenced phenotype with decreases in central memory markers SELL and CCR7, and GTP‐binding member GIMAP7 and upregulation of MMP2 inhibitor TIMP2 and tumour suppressor gene RUNX3.
