Project description:Transcriptomic studies of human tumor xenografts are complicated by the presence of murine cellular mRNA. As such, it is useful to know the extent to which mouse mRNA cross-hybridizes to any given array platform. In this study, murine cDNA samples from diverse sources were hybridized to Affymetrix Human Genome U133 Plus 2.0 Arrays. In this regard it is possible to identify specific probes that are potential targets of cross-species interference. Array data was generated for 5 different mouse cDNAs and 5 different human cDNAs hybridized to human Affymetrix U133 Plus 2 arrays [3 replicates for each biological sample]. Samples included A) mouse and B) human universal RNA (Strategene, La Jolla, CA), C) B16F10 murine melanoma tumor and D) skin from same model [C57BL/6 mice] E) COLON-26 murine tumor xenograft and F) skin from same model [Balb/C mice] G) NCI-H522 human lung carcinoma xenograft and H) skin from same model (nude mice) I) LOX-IMVI human melanoma xenograft and J) skin from same model (nude mice).

Project description:Immune checkpoint inhibitors (ICIs) targeting PD-1 and CTLA-4 are essential components of the cancer therapeutic armamentarium. The remarkable responses seen with ICIs however, are also accompanied by immune-related adverse events (irAEs). These inflammatory side-effects impact virtually all organ systems, with the most common being the skin and gastrointestinal tract. Here, we establish a mouse model of commensal bacteria-driven skin irAEs and demonstrate that immune checkpoint blockade aberrantly unleashes commensal-specific T cell responses. Such responses caused widespread immune cell infiltration and inflammation throughout the skin, recapitulating the skin irAEs seen in patients treated with ICIs. This skin inflammation was dependent on production of the cytokine IL-17 by commensal-specific T cells, which in turn induced hyperactive responses from macrophages and myeloid cells. Importantly, these responses had long-term consequences, with commensal-specific T cells elicited in the context of ICIs being highly sensitive to re-activation by commensals months later. Together, our results establish a mouse model of skin irAEs and show that immune checkpoint blockade can potentiate aberrant immunity to skin commensals with long-lasting consequences.

Project description:We demonstrated that a visceral immunosuppressive tumor can influence a distant, normally-responsive tumor, located in the skin and rend it resistant to a particular immunotherapy. Examination of the transcriptome of sub-cutaneous tumors that were growing in a mouse model, in the presence or in the absence of a concomitant intra-kidney immunosuppressive tumor

Project description:To test gene expression changes of human cancer cells and mouse surrounding tissue cells during tumor progression, 4 different types of cancer cells (MDA-MB231Br3, PC14Br4, KM12M, A375SM) were injected into mouse brain, skin and orthotopic sites. RNAs containing human cancer cells and mouse surrounding tissue cells were extracted and hybridized into human and mouse arrays at the same times and it revealed the brain microenvironment induced complete reprogramming of metasized cancer cells, resulting in a gain of neuronal cell characteristic , mimicking neurogenesis during development.

Project description:Atopic dermatitis (AD) typically starts in infancy or early childhood, showing spontaneous remission in a subset of patients, while others develop lifelong disease. Despite an increased understanding of AD, factors guiding its natural course are only insufficiently elucidated. We thus performed suction blistering in skin of adult patients with stable, spontaneous remission from previous moderate-to-severe AD during childhood. Samples were compared to healthy controls without personal or familial history of atopy, and to chronic, active AD lesions. Skin cells and tissue fluid obtained were used for single-cell RNA sequencing and proteomic multiplex assays, respectively. We found overall cell composition and proteomic profiles of spontaneously healed AD to be comparable to healthy control skin, without upregulation of typical AD activity markers (e.g., IL13, S100As, and KRT16). Among all cell types in spontaneously healed AD, melanocytes harbored the largest numbers of differentially expressed genes in comparison to healthy controls, with upregulation of potentially anti-inflammatory markers such as PLA2G7. Conventional T-cells also showed increases in regulatory markers, and a general skewing toward a more Th1-like phenotype. By contrast, gene expression of regulatory T-cells and keratinocytes was essentially indistinguishable from healthy skin. Melanocytes and conventional T-cells might thus contribute a specific regulatory milieu in spontaneously healed AD skin.
