Single‐Cell Insights Into Pathogenic Profile of Orchitis and SREBP2‐Associated Cholesterol Dysregulation in Spermatogenic Failure

open access: yesAdvanced Science, EarlyView.
A first single‐cell atlas of human orchitis reveals coordinated germ‐cell loss, somatic niche dysfunction, and immune‐metabolic remodeling. Aberrant SREBP2 activation in testicular somatic cells emerges as a central pathogenic node, while Fatostatin‐mediated inhibition of the SREBP pathway improves spermatogenesis, fibrosis, and lipid accumulation in a

Interferon-gamma excess leads to pathogenic accumulation of follicular helper T cells and germinal centers

open access: yes, 2012
SummaryOveractivity of the germinal center (GC) pathway resulting from accumulation of follicular helper T (Tfh) cells causes autoimmunity, underscoring the need to understand the factors that control Tfh cell homeostasis.

CD86‐Positive Mature Tertiary Lymphoid Structures Are Associated With CD8+ T‐Cell Infiltration and Favorable Clinical Outcomes in Pancreatic Ductal Adenocarcinoma

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
CD86‐positive mature tertiary lymphoid structures were associated with increased intratumoral CD8+ T‐cell infiltration, a higher proportion of Granzyme B‐expressing CD8+ T cells in an exploratory analysis, and favorable clinical outcomes in pancreatic ductal adenocarcinoma.

Interconnected subsets of memory follicular helper T cells have different effector functions

open access: yes, 2017
Follicular helper T cells regulate high-affinity antibody production. Memory follicular helper T cells can be local in draining lymphoid organs and circulate in the blood, but the underlying mechanisms of this subdivision are unresolved.

Proteomic Profiling of Nodal T‐Follicular Helper Cell Lymphoma Reveals Distinct Biological Signatures and Improves Prognostic Stratification Beyond the IPI

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Nodal T‐follicular helper cell lymphoma (nTFHL), most commonly of angioimmunoblastic type, exhibits heterogeneous clinical outcomes that are not fully explained by current clinical and biological variables. While genetic alterations have been extensively investigated, its proteomic landscape remains largely unexplored.

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

open access: yesThe Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

open access: yesThe Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

open access: yesAnimal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.
