A unique chemically induced proximity method is engineered based on mutant antibody VL domain using a fluorogenic malachite green derivative as the inducer, which gives fluorescent signals upon VL domain dimerization while simultaneously inducing downstream biological effects.

Background: Millions worldwide are exposed to elevated levels of arsenic that significantly increase their risk of developing atherosclerosis, a pathology primarily driven by immune cells. While the impact of arsenic on immune cell populations in atherosclerotic plaques has been broadly characterized, cellular heterogeneity is a substantial barrier to in-depth examinations of the cellular dynamics for varying immune cell populations.
Objectives: This study aimed to conduct single-cell multi-omics profiling of atherosclerotic plaques in apolipoprotein E knockout () mice to elucidate transcriptomic and epigenetic changes in immune cells induced by arsenic exposure.

Manganese (Mn) is a neurotoxin that has been etiologically linked to the development of neurodegenerative diseases in the case of overexposure. It is widely accepted that overexposure to Mn leads to manganism, which has clinical symptoms similar to Parkinson's disease (PD), and is referred to as parkinsonism. Astrocytes have been reported to scavenge and degrade extracellular α-synuclein (α-Syn) in the brain.

Leukemia is a prevalent cancer that severely affects children, and standard chemotherapy often leads to severe gastrointestinal symptoms and neutropenia. This study aimed to discover alternative treatments to prevent neutropenia in pediatric leukemia patients and minimize chemotherapy-related complications. This randomized, placebo-controlled trial was conducted on 52 children between the ages of 3 and 18 years who were suffering from acute leukemia and undergoing chemotherapy.

As natural agonists of the stimulator of interferon genes (STING) protein, cyclic dinucleotides (CDNs) can activate the STING pathway, leading to the expression of type I interferons and various cytokines. Efficient activation of the STING pathway in antigen-presenting cells (APCs) and tumor cells is crucial for antitumor immune response. Tumor-derived exosomes can be effectively internalized by APCs and tumor cells and have excellent potential to deliver CDNs to the cytoplasm of APCs and tumor cells.

Background: Thromboembolic events are a common cause of morbidity and mortality in patients with cancer. While direct-acting oral anticoagulants (DOACs) have been established as the preferred agents of anticoagulation in most patients with cancer, data in resource-limited settings is limited.
Aims: The study aims to assess the comparative efficacy and safety of warfarin and rivaroxaban for cancer-associated thrombosis (CAT) in a resource-limited setting.
