PLCB2 and viral infectious disease: An RNAscope antisense probe specific to the genomic positive strand RNA (for proof of viral infection) of the spike protein (S) sequence of SARS-CoV-2 and a sense probe specific to the ORF1ab negative strand RNA (for proof of viral replication) indicated the presence of replicating SARS-CoV-2 in PLCB2 positive cells (participant #114; Figure 2C).
