Oral Immunization with Recombinant Saccharomyces cerevisiae expressing TM1 of Mycoplasma gallisepticum induces Unique Specific Antibodies and Protective Immunity.

Mycoplasma gallisepticum (MG) is one of the main pathogens causing chronic respiratory diseases in chickens, which seriously affects the sustainable and healthy development of the poultry industry and leading to heavy economic losses. Therefore, we developed a safe, efficient, convenient, and low-cost MG oral vaccine. The vaccine is based on a recombinant yeast surface display system to compensate for the shortcomings of existing vaccines.

Quercetin and AMPK: A Dynamic Duo in Alleviating MG-Induced Inflammation via the AMPK/SIRT1/NF-κB Pathway.

(MG) is recognized as a principal causative agent of avian chronic respiratory disease, inflicting substantial economic losses upon the poultry industry. However, the extensive use of conventional antibiotics has resulted in the emergence of drug resistance and various challenges in their clinical application. Consequently, there is an urgent need to identify effective therapeutic agents for the prevention and treatment of mycoplasma-induced respiratory disease in avian species.

BIK1 protein homeostasis is maintained by the interplay of different ubiquitin ligases in immune signaling.

Pathogen-associated molecular patterns (PAMPs) trigger plant innate immunity that acts as the first line of inducible defense against pathogen infection. A receptor-like cytoplasmic kinase BOTRYTIS-INDUCED KINASE 1 (BIK1) functions as a signaling hub immediately downstream of multiple pattern recognition receptors (PRRs). It is known that PLANT U-BOX PROTEIN 25 (PUB25) and PUB26 ubiquitinate BIK1 and mediate BIK1 degradation.

Visible-light organophotoredox-mediated intermolecular formal [4 + 2] cycloadditions of arylcyclobutylamines with olefins.

We have developed a visible-light-mediated formal [4 + 2] cycloaddition of arylcyclobutylamines with olefins, using QXPT-NPhCN as an organic photocatalyst. The corresponding cycloadducts could be obtained from electron-deficient olefins, aryl olefins and exocyclic olefins. We found that the addition of KPO could significantly promote the cycloadditions.

High-Efficiency Thermal-Annealing-Free Organic Solar Cells Based on an Asymmetric Acceptor with Improved Thermal and Air Stability.

The stability of organic solar cells (OSCs) is an urgent problem for commercialization. In this work, a novel asymmetric molecule TB-4Cl was designed and synthesized. Quantum chemical computations revealed that TB-4Cl has a larger dipole moment of 1.

Identification of critical cysteine sites in brassinosteroid-insensitive 1 and novel signaling regulators using a transient expression system.

The plant hormones brassinosteroids (BRs) modulate plant growth and development. Cysteine (Cys) residues located in the extracellular domain of a protein are of importance for protein structure by forming disulfide bonds. To date, the systematic study of the functional significance of Cys residues in BR-insensitive 1 (BRI1) is still lacking.

Stat3-Atg5 signal axis inducing autophagy to alleviate hepatic ischemia-reperfusion injury.

In performing our experiment, impaired autophagy increased hepatocellular damage during the reperfusion period. It was demonstrated by the effect of blocking autophagy using bafilomycin A1 or knocking Atg5 gene out reduces the anti-apoptotic effect of Stat3. Here we focus on the role of signal transducer and activator of transcription 3 (Stat3) in regulating autophagy to alleviate hepatic IRI.

Comparative study of Arabidopsis PBS1 and a wheat PBS1 homolog helps understand the mechanism of PBS1 functioning in innate immunity.

Arabidopsis AVRPPHB SUSCEPTIBLE1 (PBS1) serves as a "decoy" in activating RESISTANCE TO PSEUDOMONAS SYRINGAE5 (RPS5) upon cleavage by Pseudomonas phaseolicola B (AvrPphB), a Pseudomonas syringae effector. The SEMPH motif in PBS1 was thought to allow it to be distinguished by RPS5 from the closely related Arabidopsis kinases. However, the underlying mechanism is not fully understood.

Reconstitution of the plant ubiquitination cascade in bacteria using a synthetic biology approach.

Ubiquitination modulates nearly all aspects of plant life. Here, we reconstituted the Arabidopsis thaliana ubiquitination cascade in Escherichia coli using a synthetic biology approach. In this system, plant proteins are expressed and then immediately participate in ubiquitination reactions within E.
