Excited to introduce scKINETICS, an algorithm for joint inference of gene regulatory mechanism and cellular velocity, co-developed by the amazing duo of @CassBurdziak and @juuuulianaar

Happy to have contributed to this paper as a bioinformatician during my stay @CIML_Immunology as a PhD Student in lab of @DalodCiml, this paper was a collaboration between @LawrenceTobyLab and @DalodCiml
@ColtEgelston@simocristea being a bioinformatician it is also confusing for me, I was also informed that for cDC1 (DC1) maturation and activation are same and for pDC (plasmacytoid DC) there are various stages of activation, 1st no IFN, then IFN+, then IFN+++, then again no IFN, then pDC become like cDC1
Incredibly proud to see our benchmark of single-cell preprocessing methods finally published 🥳🥳🎉
We show that despite its theoretical limitations, no other transformation consistently outperforms log(y/s+1).

@arjunrajlab indeed it is always better to confirm your results of trajectory inference through another tool like the ones based on transcription dynamics.
You can reproduce the whole analysis using the docker image or you can use it to analyze your scRNA data as well. The whole code along with link to the docker image is provided here (https://t.co/YvNGIqefA9)
Published in this book (https://t.co/rSEgrtxSO2) is also my book chapter titled "Harnessing gene expression profiling to infer the activation states of dendritic cell types,
their dynamical relationships and their molecular regulation" for single cell RNA-seq data analysis.
After getting bonafide cDC1 we performed trajectories inference using monocle and velocyto. We found two distinct trajectories for cDC1 in normal vs tumor bearing lungs through monocle and velocyto.
Interestingly, velocyto (which relies on transcrinal dynamics of the genes within cell) was more robust for prediciting cDC1 fate within two different pathophysiological contexts whereas monocle required separating the analysis for the two different conditions.
During cell type identification, difficult part was to discriminate cDC1 from cDC2 upon maturation which is notoriously difficult to based only on gene expression. For cell type identification instead of relying on cluster-based approach we used a sc-based approach.
In this protocol we tried to find the activation trajectory of cDC1 in two different pathophysiological contexts (tumor vs normal conditions). Therefore, we used the data single cell RNA seq data from this paper as a reference (https://t.co/cfn8wxQ5AO).
The book chapter provides a detailed description for each step of the single cell RNA Seq data starting from the raw sequencing counts until the biological interpretation of results.
I’m thrilled to share the @VardhanaLab’s first true pre-print led by @MisekerAbate, an equal collaboration with the brilliant @VStrongMD exploring the immune landscape of gastric adenocarcinoma (supported by @Cycle4Survival ). A brief tweetorial:
