Interleukin-7 links T lymphocyte and intestinal epithelial cell homeostasis. [PDF]

PLoS ONE, 2012
Interleukin-7 (IL-7) is a major survival factor for mature T cells. Therefore, the degree of IL-7 availability determines the size of the peripheral T cell pool and regulates T cell homeostasis.

IL-7 and IL-7R in health and disease: An update through COVID times

Advances in Biological Regulation, 2023
The role of IL-7 and IL-7R for normal lymphoid development and an adequately functioning immune system has been recognized for long, with severe immune deficiency and lymphoid leukemia as extreme examples of the consequences of deregulation of the IL-7-IL-7R axis.

Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

Advanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

Deficiency of IL-7R attenuates abdominal aortic aneurysms in mice by inhibiting macrophage polarization towards M1 phenotype through the NF-κB pathway

Molecular Medicine
Background Abdominal aortic aneurysm (AAA) is a common degenerative disease of the abdominal aorta, which can result in extremely high mortality owing to the rupture of the abdominal aorta.

Isocyanate‐Modified Melatplatin(IV) Enhances Antitumor Efficacy via TCF4/COL6A3‐Mediated Extracellular Matrix Remodeling and cGAS‐STING Pathway Activation in Bladder Cancer

Advanced Science, EarlyView.
A series of melatonin‐conjugated platinum(IV) prodrugs was functionalized with isocyanate chains (compounds 5‒12). MP‐12C (compound 11) was identified as the lead candidate, with optimal potency and safety. MP‐12C exhibited greater efficacy than cisplatin by increasing intracellular uptake, reshaping the extracellular matrix, activating the cGAS‐STING ...

Meningeal Lymphatic LTBR Deficiency Links Spinal Cord Injury to Secondary Brain Pathology

Advanced Science, EarlyView.
Spinal cord injury (SCI) induces remote brain alterations beyond the injured spinal cord. This study links dysfunction of meningeal lymphatic vessels (mLVs) to neuroinflammation and neuronal injury after SCI. LTBR‐mediated lymphatic restoration improves meningeal lymphatic integrity and neurological outcomes, highlighting LTBR as a potential regulator ...

Microbial metabolite indole‐3‐propionic acid preserves astrocytic mitochondrial mitofusin 2 to limit neuroinflammation after traumatic brain injury

Interdisciplinary Medicine, EarlyView.
Following traumatic brain injury, indole‐3‐propionic acid (IPA) directly targets the aryl hydrocarbon receptor on astrocytes in the peri‐lesional cortex; this suppresses interferon regulatory factor 1‐driven transcription of the E3 ubiquitin ligase RFFL (ring finger and FYVE‐like domain containing E3 ubiquitin protein ligase).

Shikonin Promotes Apoptosis in Multiple Myeloma Cells Through the PKM2‐AMPK‐PGC1α Metabolic Axis

Journal of Clinical Laboratory Analysis, EarlyView.
High PKM2 expression in MM is associated with a poor prognosis. Shikonin represents a promising PKM2‐targeted agent for MM therapy, offering a unique metabolic intervention strategy to improve drug resistance, bone disease, and the immune microenvironment. ABSTRACT Background Multiple myeloma (MM) is an incurable plasma malignancy.
