Outcome of Transjugular Intrahepatic Portosystemic Shunt in Patients with Cirrhosis and Refractory Hepatic Hydrothorax: A Systematic Review and Meta-analysis.

 Around 5% of patients with cirrhosis of the liver develop hepatic hydrothorax (HH). For patients with refractory HH (RHH), transjugular intrahepatic portosystemic shunt (TIPS) has been investigated in small studies. Hence, the present meta-analysis aimed to summarize the current data on the outcome of TIPS in patients with RHH.

Machine learning has proven exceptionally competent in numerous applications of studying dynamical systems. In this article, we demonstrate the effectiveness of reservoir computing, a famous machine learning architecture, in learning a high-dimensional spatiotemporal pattern. We employ an echo-state network to predict the phase ordering dynamics of 2D binary systems-Ising magnet and binary alloys.

RIPosomes are targets of IRGM-SQSTM1-dependent autophagy.

The NOD1-NOD2-RIPK2-NFKB/NF-κB pro-inflammatory axis plays a significant role in regulating the immune response to bacterial infection. However, an excess of NFKB-dependent cytokine response can be detrimental and, thus, should be kept under control to maintain the innate immune balance. In our recent study, first, we showed that bacterial infection induces the biogenesis of RIPK2 oligomers (RIPosomes) that are recruited around the bacteria to enhance an NFKB-dependent pro-inflammatory response.

Selective autophagy of RIPosomes maintains innate immune homeostasis during bacterial infection.

The NOD1/2-RIPK2 is a key cytosolic signaling complex that activates NF-κB pro-inflammatory response against invading pathogens. However, uncontrolled NF-κB signaling can cause tissue damage leading to chronic diseases. The mechanisms by which the NODs-RIPK2-NF-κB innate immune axis is activated and resolved remain poorly understood.

Interactions of Autophagy and the Immune System in Health and Diseases.

Autophagy is a highly conserved process that utilizes lysosomes to selectively degrade a variety of intracellular cargo, thus providing quality control over cellular components and maintaining cellular regulatory functions. Autophagy is triggered by multiple stimuli ranging from nutrient starvation to microbial infection. Autophagy extensively shapes and modulates the inflammatory response, the concerted action of immune cells, and secreted mediators aimed to eradicate a microbial infection or to heal sterile tissue damage.

Innate immunity and inflammophagy: balancing the defence and immune homeostasis.

Extensive crosstalk exists between autophagy and innate immune signalling pathways. The stimuli that induce pattern recognition receptor (PRR)-mediated innate immune signalling pathways, also upregulate autophagy. The purpose of this increased autophagy is to eliminate the stimuli and/or suppress the inflammatory pathways by targeted degradation of PRRs or intermediary proteins (termed 'inflammophagy').

IRGM links autoimmunity to autophagy.

IRGM is a genetic risk factor for several autoimmune diseases. However, the mechanism of IRGM-mediated protection in autoimmunity remains undetermined. The abnormal activation of type I interferon (IFN) response is one of the significant factors in the pathogenesis of several autoimmune diseases.

Autoimmunity gene IRGM suppresses cGAS-STING and RIG-I-MAVS signaling to control interferon response.

Activation of the type 1 interferon response is extensively connected to the pathogenesis of autoimmune diseases. Loss of function of Immunity Related GTPase M (IRGM) has also been associated to several autoimmune diseases, but its mechanism of action is unknown. Here, we found that IRGM is a master negative regulator of the interferon response.

TRIM16 employs NRF2, ubiquitin system and aggrephagy for safe disposal of stress-induced misfolded proteins.

The cellular stresses, genetic mutations, and environmental factors can critically affect the protein quality control checkpoints resulting in protein misfolding. Molecular chaperones play a crucial role in maintaining the healthy proteome by refolding the misfolded proteins into the native functional conformations. However, if they fail to refold the misfolded proteins into the native state, they are targeted by proteolytic systems for degradation.

IRGM restrains NLRP3 inflammasome activation by mediating its SQSTM1/p62-dependent selective autophagy.

We recently showed that TRIM16 acts as a key regulatory protein to control the biogenesis and degradation of protein aggregates.

The Crohn's Disease Risk Factor IRGM Limits NLRP3 Inflammasome Activation by Impeding Its Assembly and by Mediating Its Selective Autophagy.

Several large-scale genome-wide association studies genetically linked IRGM to Crohn's disease and other inflammatory disorders in which the IRGM appears to have a protective function. However, the mechanism by which IRGM accomplishes this anti-inflammatory role remains unclear. Here, we reveal that IRGM/Irgm1 is a negative regulator of the NLRP3 inflammasome activation.

TRIM16 controls turnover of protein aggregates by modulating NRF2, ubiquitin system, and autophagy: implication for tumorigenesis.

Protein misfolding and protein aggregation are linked to several diseases commonly called as proteinopathies, which include cancer. Understanding the mechanisms of proteostasis could provide newer strategies to combat proteinopathies. We have recently demonstrated a new mechanism where we found that TRIM16 (tripartite motif-containing protein 16) utilizing NRF2-p62 axis and autophagy streamlines the safe disposal of misfolded proteins to maintain protein homeostasis.

TRIM16 controls assembly and degradation of protein aggregates by modulating the p62-NRF2 axis and autophagy.

Sequestration of protein aggregates in inclusion bodies and their subsequent degradation prevents proteostasis imbalance, cytotoxicity, and proteinopathies. The underlying molecular mechanisms controlling the turnover of protein aggregates are mostly uncharacterized. Herein, we show that a TRIM family protein, TRIM16, governs the process of stress-induced biogenesis and degradation of protein aggregates.

Trypanosomatids are pathogenic protozoa of the order Kinetoplastida. A unique feature of these parasitic protozoa is the presence of a unique dithiol trypanothione (N(1), N(8) -bis(glutathionyl)spermidine) and the flavoenzyme trypanothione reductase. This is in contrast to human and other eukaryotes, which contain ubiquitous glutathione/glutathione reductase system.
