Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Th1-like Plasmodium-Specific Memory CD4+ T Cells Support Humoral Immunity

Cell Reports, 2017
Summary: Effector T cells exhibiting features of either T helper 1 (Th1) or T follicular helper (Tfh) populations are essential to control experimental Plasmodium infection and are believed to be critical for resistance to clinical malaria.

Life of T Follicular Helper Cells

Molecules and Cells, 2015
Antibodies are powerful defense tools against pathogens but may cause autoimmune diseases when erroneously directed toward self-antigens. Thus, antibody producing cells are carefully selected, refined, and expanded in a highly regulated microenvironment (germinal center) in the peripheral lymphoid organs.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Mapping the Lineage Relationship between CXCR5+ and CXCR5− CD4+ T Cells in HIV-Infected Human Lymph Nodes

Cell Reports, 2019
Summary: CXCR5 is a key marker of follicular helper T (TFH) cells. Using primary lymph nodes (LNs) from HIV-infected patients, we identified a population of CXCR5− CD4+ T cells with TFH-cell-like features.

CAR NK Cell Therapy for T Follicular Helper Cells

Cell Reports Medicine, 2020
T follicular helper (TFH) cells are associated with the development of both autoimmune disease and T cell malignancies. In this issue, Reighard et al.,1 describe the design of PD-L1 chimeric antigen receptor (CAR) NK cells that effectively target and ...

T Follicular Helper Cell Heterogeneity

Annual Review of Immunology
T follicular helper (Tfh) cells specialize in helping B cells and are therefore critical contributors to the generation of humoral immunity. Tfh cells aid immunoglobulin class-switch recombination and support the germinal center response, thereby promoting immunoglobulin affinity maturation and the generation of humoral immune memory.

MicroRNAs, T follicular helper cells and inflammaging

Oncotarget, 2015
Advanced age is associated with a declining ability to mount satisfactory immune responses (i.e. immunosenescence) resulting in increased infection susceptibility and diminished vaccine-elicited immune responses. Paradoxically, aged individuals also have a reduced ability to resolve certain types of inflammation (i.e.

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

FEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...
