HTGTS‐TCR‐Seq for Profiling of Mouse and Human T‐Cell Receptor α and β Gene Rearrangements and Diversity

Advanced Science, EarlyView.
HTGTS‐TCR‐seq is an efficient and cost‐effective method for profiling TCRα and TCRβ rearrangements using only a few primers. It captures both productive and nonproductive recombination events, minimizes primer bias, and reveals stage‐specific and age‐related repertoire changes in mice, as well as conserved features in human peripheral T cells ...

Stress‐Induced Activation of Prolactin‐NR4A1‐Midkine Axis Exacerbates Skin Inflammation

Advanced Science, EarlyView.
Chronic psychological stress activates prolactin signaling to reprogram dermal fibroblasts into APCDD1+ inflammatory effectors via NR4A1, driving midkine secretion. This paracrine hub amplifies keratinocyte proliferation and immune recruitment, thus exacerbating skin inflammation.

Morphological and Hyperphosphorylation Transitions of Nanoscale Tau Aggregates in Alzheimer's Disease

Advanced Science, EarlyView.
Super‐resolution microscopy identifies nano‐sized tau aggregates (nano‐aggregates) and reveals distinct transitions in their morphology and phosphorylation profiles across control, Primary Age‐Related Tauopathy, and Alzheimer's disease brains. Morphology and hyperphosphorylation signatures distinguish physiological from pathological forms, with nano ...

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

Advanced Science, EarlyView.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

Minimum Variance Unbiased Estimation and Certain Problems of Additive Number Theory

The Annals of Mathematical Statistics, 1963
Let $T$ be a subset of the set $I$ of non-negative integers. Define $f(\theta) = \sum a(x)\theta^x$ where the summation extends over $T$ and $a(x) > 0, \theta \geqq 0$ with $\theta \epsilon \Theta$, the parameter space, such that $f(\theta)$ is finite and differentiable.

Type I Interferon Pathway Activation Disrupts Monocyte Maturation and Enhances Immune Evasion in Multiple Myeloma

Advanced Science, EarlyView.
This study shows that monocytes in multiple myeloma display an excessive interferon response, leading to transcriptional reprogramming and altered differentiation. Using single‐cell sequencing, coculture experiments, and patient samples before and after therapy, the authors demonstrate that induction treatment reduces this interferon response ...

Single‐Position Peptide Clustering for Peptidomics Reveals Novel Disease Biomarkers and Dysregulated Proteolytic Characteristics

Advanced Science, EarlyView.
A novel amino acid (aa)‐score‐based single‐position peptide clustering strategy is developed for peptidomics, enabling precise profiling of protein proteolysis in plasma from β‐thalassemia cohort. The method identifies new aa position‐based peptide cluster biomarkers validated by heavy‐labeled peptides, visualizes aggregated changes, uncovers disease ...
