Memory CD8(+) T cell heterogeneity is primarily driven by pathogen-specific cues and additionally shaped by the tissue environment
Factors that govern the complex formation of memory T cells are not completely understood. A better understanding of the development of memory T cell heterogeneity is however required to enhance vaccination and immunotherapy approaches. Here we examined the impact of pathogen- and tissue-specific cues on memory CD8(+) T cell heterogeneity using high-dimensional single-cell mass cytometry and a tailored bioinformatics pipeline. We identified distinct populations of pathogen-specific CD8(+) T cells that uniquely connected to a specific pathogen or associated tomultiple types of acute and persistent infections. In addition, the tissue environment shaped the memory CD8(+) T cell heterogeneity, albeit to a lesser extent than infection. The programming of memory CD8(+) T cell differentiation during acute infection is eventually superseded by persistent infection. Thus, the plethora of distinct memory CD8(+) T cell subsets that arise upon infection is dominantly sculpted by the pathogen-specific cues and further shaped by the tissue environment.Radiolog

Chemically engineered glycan-modified cancer vaccines to mobilize skin dendritic cells
Dendritic cell (DC)ātargeting vaccines show great promise in increasing antitumor immunity. Glycan-engineered vaccines facilitate both DC targeting and increased uptake by DCs for processing and presentation to CD4+ and CD8+ T cells to induce tumor-specific T-cell responses. However, the complexity of various DC subsets in skin tissues, expressing different glycan-binding receptors that can mediate vaccine uptake or drainage of vaccines via lymphatics directly to the lymph nodeāresident DCs, complicates the success of vaccines. Moreover, the influx of inflammatory immune cells to the site of vaccination, such as monocytes that differentiate to DCs and coexpress glycan-binding receptors, may contribute to the strength of DC-targeting glycovaccines for future clinical use

Memory CD8<sup>+</sup> T cell heterogeneity is primarily driven by pathogen-specific cues and additionally shaped by the tissue environment
SummaryFactors that govern the complex formation of memory T cells are not completelyunderstood. A better understanding of thedevelopment of memory Tcell hetero-geneity is however required to enhance vaccination and immunotherapy ap-proaches. Here we examined the impact of pathogen- and tissue-specific cueson memory CD8+T cell heterogeneity using high-dimensional single-cell mass cy-tometry and a tailored bioinformatics pipeline. We identified distinct populationsof pathogen-specific CD8+T cells that uniquely connected to a specific pathogenor associated to multiple types of acute and persistent infections. In addition, thetissue environment shaped the memory CD8+T cell heterogeneity, albeit to alesser extent than infection. The programming of memory CD8+T cell differenti-ation during acute infection is eventually superseded by persistent infection.Thus, the plethora of distinct memory CD8+T cell subsets that arise upon infec-tion is dominantly sculpted by the pathogen-specific cues and further shaped by the tissue environment.Pattern Recognition and Bioinformatic
