IGFBP5 Restores Endometrial Receptivity and Rescues Implantation Failure in Polycystic Ovary Syndrome

open access: yesAdvanced Science, EarlyView.
Impaired endometrial receptivity contributes to the poor pregnancy outcomes in women with PCOS. The authors found that decreased endometrial IL‐22 levels and disrupted STAT3‐IGFBP5 signaling pathway contributed to impaired endometrial receptivity. Supplementation with IL‐22 or IGFBP5 exerts a protective effect on implantation failure in PCOS‐like mice,

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Chronic smoke exposure is associated with autophagy in murine Peyer's patches [PDF]

open access: yes, 2011
INTRODUCTION: Cigarette smoke causes oxidative stress, leading to smoke-induced autophagy in several organs. Autophagy is a homeostatic process regulating the turnover of proteins and cytoplasmatic organelles.

Lymphoid‐Tissue‐on‐Chip Recapitulates Human Antibody Responses In Vitro

open access: yesAdvanced Science, EarlyView.
The presented lymphoid‐tissue‐on‐chip system allows culture of primary human tonsil cells at organotypic high density under perfusion for up to 4 weeks, emulates immune response to soluble vaccines and vaccination via peripheral antigen‐presenting cells and represents a useful tool to assess cellular interactions during homeostasis, immune responses ...

A Cell Migration Tracking Tool Supports Coupling of Tissue Rotation to Elongation

open access: yesCell Reports, 2017
Cell migration is indispensable to morphogenesis and homeostasis. Live imaging allows mechanistic insights, but long-term observation can alter normal biology, and tools to track movements in vivo without perturbation are lacking.

Single‐Cell Dissection of Tumor‐Infiltrating Lymphocytes Reveals Cellular Architecture Predictive of Therapeutic Efficacy in Acral Melanoma

open access: yesAdvanced Science, EarlyView.
Autologous tumor‐infiltrating lymphocyte (TIL) therapy shows promising efficacy in acral melanoma, yet determinants of durable response remain unclear. By integrating single‐cell transcriptomics and TCR sequencing, this study reveals that TIL products enriched for T follicular helper and intermediate exhausted T cells establish persistent clonal ...

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

open access: yesAdvanced Science, EarlyView.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]

open access: yes, 2007
Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To

Sertoli Cell‐Derived Extracellular Vesicles Orchestrate Cadmium‐Induced Testicular Inflammation and Fibrosis

open access: yesAdvanced Science, EarlyView.
Environmental cadmium exposure disrupts testicular homeostasis through a novel intercellular communication axis. Stressed Sertoli cells release extracellular vesicles carrying damage‐associated molecular patterns and mitochondrial fragments, which activate macrophages via TLR4/NF‐κB signaling.
