Article Synopsis
  • - Glucosylceramidase beta 1 (GBA1) mutations increase the risk of Parkinson's disease (PD), but many carriers don't develop symptoms; this study explores factors that may influence PD development in GBA1 carriers.
  • - The research used a database with participants divided into non-manifesting GBA1 carriers, controls, and those with GBA1-associated PD, analyzing exposure to pesticides, smoking, and other factors in relation to PD risk and symptoms.
  • - Findings indicated that pesticide exposure was linked to a higher risk of PD in GBA1 carriers, while smoking seemed to lower that risk; however, early-stage GBA1-associated PD had more severe symptoms than non-manifesting carriers,

Liposomes, especially polyethylene glycol (PEG)-modified long-circulating liposomes, have been approved for market use, due to good biocompatibility, passive tumor targeting, and sustained drug release. PEG-modified long-circulating liposomes address issues such as poor stability and rapid clearance by the reticuloendothelial system. However, they still face challenges like hindering drug uptake by tumor cells and preventing tumor penetration.

The immunosuppressive microenvironment severely limits the responsiveness of colorectal cancer (CRC) to immunotherapy. Herein, a pH and reactive oxygen species (ROS) dual-responsive autocatalytic release system (TPDM/PGA) is constructed to reverse the immunosuppressive microenvironment and potentiate CRC immunotherapy. Dihydroartemisinin (DHA) and mitoxantrone (MTO) are conjugated to ROS-responsive polyethylenimine (TP) via a ROS-cleavable linker, respectively, and then coated with polyglutamic acid (PGA) to endow pH and ROS dual-responsiveness.

Brain tumors such as glioblastomas are resistant to immune checkpoint blockade therapy, largely due to limited T cell infiltration in the tumors. Here, we show that mice bearing intracranial tumors exhibit systemic immunosuppression and T cell sequestration in bone marrow, leading to reduced T cell infiltration in brain tumors. Elevated plasma corticosterone drives the T cell sequestration via glucocorticoid receptors in tumor-bearing mice.

The evolving use of covalent ligands as chemical probes and therapeutic agents could greatly benefit from an expanded array of cysteine-reactive electrophiles for efficient and versatile proteome profiling. Herein, to expand the current repertoire of cysteine-reactive electrophiles, we developed a new class of strain-enabled electrophiles based on cyclopropanes. Proteome profiling has unveiled that C163 of lactate dehydrogenase A (LDHA) and C88 of adhesion regulating molecule 1 (ADRM1) are ligandable residues to modulate the protein functions.

Chemotherapy, as a conventional strategy for tumor therapy, often leads to unsatisfied therapeutic effect due to the multi-drug resistance and the serious side effects. Herein, we genetically engineered a thermal-responsive murine Ferritin (mHFn) to specifically deliver mitoxantrone (MTO, a chemotherapeutic and photothermal agent) to tumor tissue for the chemotherapy and photothermal combined therapy of colorectal cancer, thanks to the high affinity of mHFn to transferrin receptor that highly expressed on tumor cells. The thermal-sensitive channels on mHFn allowed the effective encapsulation of MTO in vitro and the laser-controlled release of MTO in vivo.
