Soluble Sema4D in plasma as an immune biomarker of non-inflamed head and neck squamous cell carcinoma profile.

Project description:This work demonstrates the potential of soluble Semaphorin 4D (sSema4D) as an immune biomarker in plasma of patients with head and neck squamous cell carcinoma (HNSCC) that can read the histological immune subtype (HIS) and IFN-γ signature of the paired tumor tissue. Advanced analysis of 10 HNSCC tumor tissue using the IO-360 nanoString platform, showed that tumors with high sSema4D in plasma (HsS4D) clustered as negative IFN-γ immune signature and were most of histologically immune Excluded (HIS‐IE). 2/3 of the tumors with low sSema4D (LsSema4D) were IFN-γ positive, and histologically inflamed as scored using Sema4D in the tumor bed. Advanced custom analysis showed the myeloid immune cell type, Wnt and TGF-beta signaling and hypoxia to predominate in the paired tumor tissue of HsS4D, while the lymphoid compartment and costimulatory signaling was more in the low sSema4D (LsS4D) with high Treg component.

Deciphering the role of tumor cell-intrinsic Sema4D in TNBC mouse tumor using single-cell RNA sequencing

Project description:Sema4D (Semaphorin 4D, also known as CD100) is a member of the class IV semaphorin family and is predominantly expressed on the surface of lymphocytes, monocytes, macrophages, and endothelial cells. The current understanding of Sema4D function is focused on its receptor-mediated signaling activities with limited data on its intrinsic mechanisms. However, the immunological roles and functional mechanism of tumor cell-intrinsic Sema4D regulating immune escape remain largely unknown. This study employs single-cell RNA sequencing (scRNA-seq) to investigate cellular and regulatory role of Sema4d in TNBC mouse tumors.

Smoking aggravates neovascular age-related macular degeneration via Sema4D-PlexinB1 axis-mediated activation of pericytes [scRNA-seq]

Project description:Age-related macular degeneration (AMD) is a prevalent neuroinflammation condition and the leading cause of irreversible blindness among the elderly population. Smoking significantly increases AMD risk, yet the mechanisms remain unclear. Here, we investigated the role of Sema4D-PlexinB1 axis in the progression of AMD, in which Sema4D-PlexinB1 is highly activated by smoking. Using patient-derived samples and mouse models, we discovered that smoking increased the presence of Sema4D on the surface of CD8+ T cells that migrated into the choroidal neovascularization (CNV) lesion via CXCL12-CXCR4 axis and interacted with its receptor PlexinB1 on choroidal pericytes. This led to ROR2-mediated PlexinB1 phosphorylation and pericytes activation, hence disrupted vascular homeostasis and promoted neovascularization. Inhibition of Sema4D reduced CNV and improved the benefit of anti-VEGF treatment. In conclusion, this study unveils the molecular mechanisms through which smoking exacerbates AMD pathology, and presents a potential therapeutic strategy by targeting Sema4D to augment current AMD treatments.

Global hypomethylation identifies loci targeted for hypermethylation in head and neck cancer: normal head and neck tissue

Project description:Genome-wide DNA methylation profiling of head and neck squamous cell carcinomas. The Illumina Infinium 27k Human DNA methylation BeadChip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in fresh-frozen tumor tissues. Samples included 91 tumors from the oralpharynx and larynx, reflecting all stages of disease, 18 normal head and neck National Disease Research Interchange (NDRI) samples, and 213 normal control blood samples. Bisulphite-converted DNA from the 18 normal head and neck samples were hybridized to the Illumina Infinium 27k Human Methylation Beadchip v1.2.
