Project description:In this study, whole blood samples were used to determine the gene expression of febrile culture confirmed enteric fever cases (ST = S. Typhi; SPT = S. Paratyphi), febrile culture negative individuals presenting to hospital in Kathamandu (sEF = suspected enteric fever), and healthy community controls (CTRL).
Project description:Non-Hodgkin Lymphoma (NHL) is the main cancer-related mortality for people living with HIV (PLWH), who have elevated risk for lymphoma relative to the general population. NHL genetic and molecular classifications have been intensely studied and correlated with clinical outcomes, but critical unanswered questions relevant to malignancy persist. For example, tumors positive for Epstein-Barr virus (EBV) account for 30-50% of HIV-associated NHLs, are particularly aggressive, and have poorer clinical outcomes – yet insights on the nature of EBV in NHL pathogenesis or potential therapeutic vulnerabilities have been limited. Here, we examined HIV-associated NHLs stratified by cell of origin (COO), molecular subtype, and EBV status using genome-wide spatial transcriptomic analyses.
Project description:Chronic pruritus is a pathological condition associated with numerous systemic, dermatologic, and neurologic disorders. Chronic pruritus of unknown origin (CPUO) represents a distinct clinical subtype characterized by persistent itch without an identifiable underlying cause. While emerging evidence implicates neuroimmune dysregulation in chronic pruritus, the specific mechanisms driving CPUO remain poorly understood. Objective: To characterize the neuroimmune mechanisms underlying CPUO, with a focus on identifying potential diagnostic markers. Single-cell RNA sequencing of peripheral blood cells from patients and healthy controls was conducted. Single-cell transcriptomic analysis revealed dysregulated monocytes and hyperactive natural killer (NK) cells overexpressing CCL3.
