Challenges and Pitfalls to Diagnosing NUTM1‐Rearranged Neoplasia of the Pancreas by Cytology and Ancillary Studies

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Fine‐needle aspiration cytology specimens are frequently utilized for ancillary studies to identify diagnostic and prognostic information. This case highlights diagnostic pitfalls and challenges in diagnosing NUTM1‐rearranged neoplasia on pancreatic cytology.

The Murine Epithelial Thymic Microenvironment Is Governed by Eph/Ephrin Signalling

open access: yesCells
Although the relevance of thymic epithelial cell–thymocyte interactions for thymus function has long been emphasised, the mechanisms that govern the biology of thymic epithelial cells (TECs) are not fully understood.

Live-cell imaging reveals the relative contributions of antigen-presenting cell subsets to thymic central tolerance

open access: yesNature Communications, 2019
Both thymic epithelial cells and dendritic cells present self antigens in the thymus to mediate thymic selection and T cell tolerance. Here the authors quantify, using two-photon live imaging of mouse thymic slices, the relative contribution of these two

Interleukin 7 from maternal milk crosses the intestinal barrier and modulates T-cell development in offspring [PDF]

open access: yes, 2011
Background Breastfeeding protects against illnesses and death in hazardous environments, an effect partly mediated by improved immune function. One hypothesis suggests that factors within milk supplement the inadequate immune response of the offspring,

Human biomarker navigator

open access: yesiMeta, EarlyView.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

Understanding the Thymic Microenvironment: the Cellular and Molecular Basis of T Cell Development

open access: yesCentral Asian Journal of Medical Sciences, 2016
Objectives: The thymus is a primary lymphoid organ that provides specialized microenvironment for T cell development. A variety of thymic stromal cells form the thymic tissue architecture and critically regulate the development and repertoire selection ...

High‐Sugar Diet and Intestinal Diseases: A Shared Microbiota–Barrier–Immunity–Metabolism Axis in Inflammatory Bowel Disease, Food Allergy, and Colorectal Cancer

open access: yesiNew Medicine, EarlyView.
ABSTRACT The global incidence of intestinal diseases—including food allergy, inflammatory bowel disease (IBD), and colorectal cancer (CRC)—continues to escalate in parallel with the expansion of the “Western diet,” within which the high‐sugar diet (HSD) has emerged as a pivotal yet under‐recognized dietary driver.

Adaptive Immunity in Marsupials

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Comparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.

Long-term persistence of functional thymic epithelial progenitor cells in vivo under conditions of low FOXN1 expression.

open access: yesPLoS ONE, 2014
Normal thymus function reflects interactions between developing T-cells and several thymic stroma cell types. Within the stroma, key functions reside in the distinct cortical and medullary thymic epithelial cell (TEC) types. It has been demonstrated that,
