SCassist: An AI Based Workflow Assistant for Single-Cell Analysis

SummarySingle-cell RNA sequencing (scRNA-seq) data analysis often involves complex iterative workflow, requiring significant expertise and time. To navigate this complexity, we have developed SCassist, an R package that leverages the power of the large language models (LLMs) to guide and enhance scRNA-seq analysis. SCassist integrates LLMs into key workflow steps, to analyze user data and provide relevant recommendations for filtering, normalization and clustering parameters. It also provides LLM guided insightful interpretations of variable features and principal components, along with cell type annotations and enrichment analysis. SCassist provides intelligent assistance using popular LLMs like Googles Gemini, OpenAIs GPT and Metas Llama3, making scRNA-seq analysis accessible to researchers at all levels. Availability and implementationThe SCassist package, along with the detailed tutorials, is available at GitHub. https://github.com/NIH-NEI/SCassist

Vectofusin-1 based T-cell transduction approach for developing murine CAR-T cells for cancer.

Gene transfer into human and murine T-cells using viral-based approaches has several promising therapeutic applications including the production of chimeric antigen receptor T-cell (CAR-T) therapy. The generation of murine CAR-T is paramount to test and validate immunocompetent mouse models for CAR-T therapy. Several viral transduction enhancers already exist for gene therapy with few limitations. In this study, we tested vectofusin-1, a short cationic peptide, as a soluble transduction enhancer for gammaretroviral transduction for the generation of anti-CD19 murine CAR-T. We found that in comparison to Retronectin, Vectofusin-1 is an equally optimal transduction enhancer for the generation of murine CAR-T cells.
