Spatial Transcriptomics and Single Cell-RNASeq Reveals Cellular Heterogeneity of SARS-CoV-2 in Lung Tissues and Global Mutational Patterns in COVID-19 Patients.

RNA viruses have high mutation frequency, quick generation periods and vast population numbers, which promote fast evolution and host environment adaptation. We integrated scRNA-seq and spatial transcriptomics to profile immune cells and viral gene expression in COVID-19. Cell types and interactions were identified using Seurat-based tools.

Intersecting SARS-CoV-2 spike mutations and global vaccine efficacy against COVID-19.

In line with encountering the world with the emergence of vaccine-resistance variants of SARS-CoV-2, 15,669,529 samples that received COVID-19 vaccines until April 2023 were investigated as two doses in the first phase and booster vaccinations in the second phase. The analysis shows that D614G and P681 mutations occurred in both phases. The E484 and Y655 mutations significantly emerged during the second phase.

Comparative Atlas of SARS-CoV-2 Substitution Mutations: A Focus on Iranian Strains Amidst Global Trends.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new emerging coronavirus that caused coronavirus disease 2019 (COVID-19). Whole-genome tracking of SARS-CoV-2 enhanced our understanding of the mechanism of the disease, control, and prevention of COVID-19.

Methods: we analyzed 3368 SARS-CoV-2 protein sequences from Iran and compared them with 15.
