Immune system activation by natural products and complex fractions: a network pharmacology approach in cancer treatment

open access: yesCell Stress, 2020
Natural products and traditional herbal medicine are an important source of alternative bioactive compounds but very few plant-based preparations have been scientifically evaluated and validated for their potential as medical treatments.

Tissue typing by unidirectional mixed lymphocyte culture. 3. The relationship of in vitro lymphocyte compatibility to renal allograft rejection [PDF]

open access: yes, 1971
We applied unidirectional MLC test to renal allograft in dogs, and investigated the correlation between the growth rates of MLC reaction and the intensity of rejection of the kidney transplants or the postoperative renal function.

Classification of acute myeloid leukemia based on multi‐omics and prognosis prediction value

open access: yesMolecular Oncology, EarlyView.
The Unsupervised AML Multi‐Omics Classification System (UAMOCS) integrates genomic, methylation, and transcriptomic data to categorize AML patients into three subtypes (UAMOCS1‐3). This classification reveals clinical relevance, highlighting immune and chromosomal characteristics, prognosis, and therapeutic vulnerabilities.

Self-renewal of double-negative 3 early thymocytes enables thymus autonomy but compromises the β-selection checkpoint

open access: yesCell Reports, 2021
Summary: T lymphocyte differentiation in the steady state is characterized by high cellular turnover whereby thymocytes do not self-renew. However, if deprived of competent progenitors, the thymus can temporarily maintain thymopoiesis autonomously.

Lymphocytic Colitis With Enterocolic Lymphocytic Phlebitis

open access: yesACG Case Reports Journal
ABSTRACT Enterocolic lymphocytic phlebitis is a rare lymphocytic vasculitis afflicting the gastrointestinal veins without involving the arterial system. Lymphocytic colitis is a more common pathology described as lymphocytic inflammation of the colonic epithelium. Concurrence of both these pathologies is extremely rare.

Anergy in self-directed B lymphocytes from a statistical mechanics perspective [PDF]

open access: yesarXiv, 2012
The ability of the adaptive immune system to discriminate between self and non-self mainly stems from the ontogenic clonal-deletion of lymphocytes expressing strong binding affinity with self-peptides. However, some self-directed lymphocytes may evade selection and still be harmless due to a mechanism called clonal anergy.

Understanding and Modelling the Complexity of the Immune System: Systems Biology for Integration and Dynamical Reconstruction of Lymphocyte Multi-Scale Dynamics [PDF]

open access: yesVirtual Physiological Human Conference 2014, Sep 2014, Trondheim, Norway, 2020
Understanding and modelling the complexity of the immune system is a challenge that is shared by the ImmunoComplexiT$^1$ thematic network from the RNSC. The immune system is a complex biological, adaptive, highly diversified, self-organized and degenerative cognitive network of entities, allowing for a robust and resilient system with emergent ...

The roles and applications of extracellular vesicles in cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicles (EVs) are minute versions of cells limited by a lipid bilayer containing cytoplasm from the cell that releases them, but without a nucleus and thus unable to self‐reproduce. EVs contain multiple molecules (proteins, lipids, glycans, and nucleic acids) they can induce complex responses in cells.

Th1 Differentiation Drives the Accumulation of Intravascular, Non-protective CD4 T Cells during Tuberculosis

open access: yesCell Reports, 2017
Recent data indicate that the differentiation state of Th1 cells determines their protective capacity against tuberculosis. Therefore, we examined the role of Th1-polarizing factors in the generation of protective and non-protective subsets of Mtb ...

Spatial Organization and Molecular Correlation of Tumor-Infiltrating Lymphocytes Using Deep Learning on Pathology Images [PDF]

open access: yes, 2018
Beyond sample curation and basic pathologic characterization, the digitized H&E-stained images of TCGA samples remain underutilized. To highlight this resource, we present mappings of tumorinfiltrating lymphocytes (TILs) based on H&E images from 13 TCGA
