Cell Type and Gene Specific Survival Analysis in scRNA-seq

Question

[Ergün]

Hi Biostars Community,

As I understand, TCGA is composed of bulk RNA-seq data from various cancer types. Is there an opportunity to perform survival analysis based on the expression of a gene that is specific to a cell type (e.g. how do cytotoxicity markers in T cells but not in NK cells affect the cancer survival)?

There are some computational methods for deconvolution of bulk RNA-seq data. However, is there a scRNA-seq related cancer cohort database?

Thank you in advance,
