Genome Aging in Women: Hematopoietic Loss of X Chromosome as An Exemplar
As studies at the intersection of genetics and aging are rapidly advancing, genome aging provides a novel mechanism by which aging phenotypes occur. In this Review, the authors examine the rise, expansion, and the consequences of X chromosome loss in female blood cells.

Thymic Involution and Function in People With HIV and General Population Controls: A Cross-Sectional Analysis From Two Danish Cohort Studies. [PDF]
Thymic involution, the age‐related replacement of thymic soft tissue by fat, has been linked to immunosenescence and chronic inflammation. Whether HIV infection affects thymic involution remains unclear. We found that people with HIV on long‐term antiretroviral therapy had more thymic tissue than controls, indicating less thymic involution. More thymic

Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Aire and Fezf2 Shape the Medullary Thymic Epithelial Cell Immunopeptidome for Central Tolerance
Central tolerance is shaped not merely by promiscuous gene expression in medullary thymic epithelial cells (mTECs), but by the subset of self‐peptides ultimately presented on MHC class II molecules. We propose a multilayered framework in which AIRE/Aire and FEZF2/Fezf2, together with specialised differentiation programmes—including thymic mimetic‐cell ...

Abstract Tumors of neuroendocrine origin are a heterogenous group of related neoplasms which can arise from anywhere in the body. Neuroendocrine neoplasms (NENs) are categorized by site of origin, differentiation status and grade (Ki‐67 expression and/or mitotic rate), with significant prognostic variability accordingly. Historically, the prevalence of

ASPECTS OF THE THYMUS (THYMUS) IN CHILDREN
A huge mystery of biology, medicine (primarily immunology) and in particular pediatrics is the thymus gland (thymus). And this despite the fact that he attracted the closest attention of researchers for 4 centuries or more.

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

IMM‐H018, a dual IDO1/NE inhibitor, demonstrates potent therapeutic efficacy in sepsis by simultaneously targeting excessive inflammation and immune dysfunction. It prevents both primary and secondary sepsis through anti‐inflammatory, immune‐restoring, and renoprotective mechanisms, reducing organ damage, improving immune homeostasis, preserving kidney

A cationic poly(disulfide)‐drug nanoplatform (LA/DexP) was developed to treat experimental autoimmune uveitis (EAU). With potent blood‐retinal barrier penetrability, LA/DexP releases DSP in response to high ROS and scavenges cfDNA to inhibit the cGAS‐STING signaling pathway.
