To link IFNγ-secretion levels of epitope-specific T-cells with their TCRαβ, we coated nanovials with pHLA-I to capture and activate epitope-specific T-cells and their secreted IFNγ, followed by index-sorting and TCRαβ sequencing. We demonstrate that nanovials are a promising tool to link single epitope-specific TCRαβ clonotypes to the cell's functional properties.

Wilms tumor 1 (WT1) is a tumor-associated antigen expressed in solid tumors and hematological malignancies. T-cell immunotherapies targeting WT1 are currently under development. To analyze endogenous T-cell responses against WT1, we trained computational models capable of detecting WT1-specific T-cell responses from T-cell receptor (TCR) sequencing data.

Introduction: Despite the success of vaccination, isolated cases of COVID-19 infection are being reported in the vulnerable subjects worldwide. Given that individuals with type-2 diabetes (T2D) often exhibit immune dysregulation, this study aimed to characterize SARS-CoV-2-specific immunity following ChAdOx1 nCoV-19 vaccination in subjects with T2D.
Methods: We recruited 55 T2D and 60 healthy control (HC) subjects and monitored their immunological parameters at baseline, 3rd, 6th, and 12th month post-ChAdOx1 nCoV-19 vaccination.

The prevalence of peanut allergy has been steadily increasing over the last decades. Among food allergies it shows the highest severity and is potentially fatal. Allergen Ara h 2 stands out as the main elicitor of allergic reactions.

Background: Ovarian cancer represents the most lethal gynecological cancer with poor response to checkpoint inhibitors. Human endogenous retroviruses (HERVs) are aberrantly expressed by tumor cells and may represent a source of shared T-cell epitopes for cancer immunotherapy regardless of the tumor mutational burden.
Methods: A transcriptomic analysis based on RNA sequencing was developed to quantify the expression of HERV-K sequences containing the selected epitopes.

Central memory CD8 T cells (T) represent the prominent memory T cell subset in human blood, yet the persistence of T cell receptor (TCR) clonotypic and transcriptional features of epitope-specific T pools across the human lifespan remains unknown. We analyzed T CD8 T cells specific for HLA-A*02:01-M1 (A2/M1; a prominent influenza epitope) in newborns, children, adults, and older adults directly ex vivo. Our data provide evidence that epitope-specific T CD8 pools dominate influenza-specific memory A2/M1CD8 T cell responses from the early childhood until old age.
