Summary: Systemic lupus erythematosus (SLE) is a chronic multi-organ autoimmune disease involving the production of a wide range of autoantibodies and complement activation. T follicular regulatory cells (TFRs) play a role in maintaining the stability of self-reactive antibodies, but they can also become pathogenic cells with potent effector functions.

Summary: Aberrant cancer metabolism, characterized by a preference for various metabolites including aerobic glycolysis and glutaminolysis, challenges the traditional static metabolic profile. Metabolic plasticity, often overlooked in therapeutic strategies, is crucial for understanding cancer bioenergetics. Standardization of metabolic readouts can provide a comprehensive metabolic picture in cancer research.

Summary: Glaucoma is a chronic neurodegenerative disorder that can cause vision loss and blindness. Recent research has found that glaucoma patients also have abnormal tau protein aggregation, suggesting similarities with other neurodegenerative disorders. Studies have shown that tau modifications play a crucial role in neuronal injury caused by ocular hypertension in glaucoma patients.

Summary: Viral infections can activate programmed cell death (PCD) pathways, including pyroptosis, apoptosis, and necroptosis. The emerging concept of PANoptosis suggests extensive crosstalk between these PCD pathways. PANoptosis plays a significant role in regulating viral infection, but it can also have different effects on host defense and viral pathogenesis.

Summary: A new small tripodal ligand L2 has been synthesized and used for lanthanide complexation, forming stable mononuclear complexes. The crystal structure of a C-3-symmetrical mononuclear complex with Eu-III exhibits a helical wrapping of binding strands around the cation, and similar complexes are formed along the Ln(III) series. Various techniques were used to characterize the complexes, indicating their moderate stability and ability to remain unchanged in large metal excess. Luminescence lifetimes confirm the complexation of trivalent lanthanide in a single well-protected coordination environment.

Summary: The study aimed to examine the relationship between team numerical advantage and match event outcomes in professional Australian football, and also analyzed how players occupy different field areas during match play. Results showed that an increased team numerical advantage led to a greater likelihood of gaining possession or generating a score, but more total players inside 50 were associated with a decrease in scoring probability. Teams were often outnumbered in their forward 50 but had a numerical advantage in the defensive 50.

Summary: Annexin A2 is a Ca2+ regulated protein that belongs to the Annexin family and is present in the cytoplasm and cell membrane. It plays a crucial role in the life cycle of viruses and is involved in the adhesion, internalization, uncoating, transport, and release of viruses. Annexin A2 also mediates the adhesion of parasites, bacteria, mycoplasma, fungi, and other pathogens to host cells, leading to infection and damage. Targeting Annexin A2 has shown promising anti-infective effects and may serve as a therapeutic approach for various infectious diseases.

Summary: Accurate structural models for rubrene were derived from synchrotron X-ray data in the temperature range of 100-300 K. The models revealed that the cofacially stacked tetracene backbone units of rubrene remain blocked with respect to each other upon cooling to 200 K and start to slip below that temperature. The blocked slippage occurs at approximately the same temperature as the hole mobility crossover. The study also found a negative correlation between the thermal expansion along the crystallographic b-axis and the widening of the angle between herringbone-stacked tetracene units, which causes the blocking between 200 and 300 K. DFT calculations further showed a discontinuity in the temperature variation of the electronic couplings associated with hole transport between the cofacially stacked tetracene backbones.

Summary: Shigella, a gram-negative bacterial pathogen, is responsible for bacillary dysentery. The lack of a licensed vaccine and the emergence of antibiotic resistance have made Shigella a priority pathogen requiring urgent attention. In this study, a Shigella-zebrafish infection model and high-content microscopy were used to develop an automated microscopy workflow to study bacterial and neutrophil interactions in vivo. Antibiotics were found to reduce bacterial burden but not neutrophil recruitment, and nalidixic acid was shown to work with leukocytes to control Shigella infection and restrict its dissemination. The researchers propose that their automated microscopy workflow can be useful in innovating infection control treatments in humans.

Summary: During Shigella invasion of host cells, it escapes to the cytosol and uses actin polymerization to spread between cells. Host cells employ cell-autonomous immune responses, including autophagy and septin cage entrapment, to restrict this spread. This study used cryo-SXT and other imaging techniques to investigate the interaction between septins, autophagy, and Shigella. The findings provide insights into the targeting of septin-caged Shigella for autophagy and the interaction between autophagy and the cytoskeleton.

Summary: By analyzing the genetic sequences of ST99 E. coli, we found that there are two subsets of strains, one with a virulence plasmid pINV and one without. The results of zebrafish infection experiments show that the virulence of ST99 E. coli is temperature-dependent. Furthermore, it was discovered that ST99 strains may have been virulent before the acquisition of pINV, indicating the importance of pINV in the dissemination of ST99 E. coli.

Summary: The discovery of CRISPR-Cas9 provides opportunities to selectively kill specific bacteria, but its delivery into bacterial cells is inefficient. In this study, the P1-derived phagemid is used to efficiently deliver the CRISPR-Cas9 chromosomal-targeting system into Escherichia coli and Shigella flexneri, achieving DNA sequence-specific killing of targeted bacterial cells. The P1 phage particles can also deliver cas9 phagemids into S. flexneri in vivo, reducing bacterial load and promoting host survival. This study demonstrates the potential of combining P1 phage-based delivery with the CRISPR system for efficient clearance of bacterial infection.

Summary: In this study, the authors found that the sensor protein PhoPR in Mycobacterium canettii strains has amino acid substitutions that affect its activity compared to Mycobacterium tuberculosis. These mutations impact the production and secretion of virulence factors, enhancing the capacity of the strains to colonize and transmit within the host. Therefore, these findings support the hypothesis that variants of the PhoPR regulatory system are key evolutionary adaptations for enhancing the epidemic capacity of tuberculosis.

Summary: The incidence of kidney disease is increasing globally, and acute kidney injury (AKI) can contribute to the development of cardio-renal syndrome (CRS) type 3. However, the mechanism behind CRS development is not fully understood. This study aimed to investigate the molecular mechanisms associated with cardiac mitochondrial impairment and its role in CRS development. The findings suggest that mitochondrial bioenergetics impairment plays a crucial role in heart damage, and the preservation of heart mitochondrial function during AKI could be a valuable strategy to prevent CRS type 3.

Summary: In response to tissue injury, the ultra-large glycoprotein von Willebrand factor (VWF) is released from endothelial storage organelles into the blood vasculature, leading to platelet recruitment. Endothelial cells have developed mechanisms, such as an actomyosin ring, to overcome the challenge of releasing VWF. Inhibiting the formation or function of these structures could be a potential therapeutic target for thrombotic diseases.
