Fig. 1. Overview of SARS-CoV-2 VOCs and the experimental approach to study the host–pathogen interactions.

Fig. 1

a The epidemiological and evolutionary tree of the SARS-CoV-2 variants (modified from Nextstrain.org), illustrating the emergence of the key SARS-CoV-2 VOCs (Alpha, Beta, Gamma, Delta, and Omicron). b Scheme of the experimental workflow: samples were collected at various time points post infection (1 hpi, 8 hpi, 16 hpi, and 36 hpi), followed by global quantitative proteomics and phosphoproteomics analyses using DIA-PASEF. c Infection progression was monitored by detecting the SARS-CoV-2 N protein through immunofluorescence microscopy. d Normalized log2-transformed intensity of SARS-CoV-2 proteins expressed during infection in the VeroE6-H10 cells. The error bars represent one standard deviation, n = 3 biological replicates.
