It’s cellular immunity, not antibodies, that probably protects against the coronavirus’s worst effects—and scientists haven’t worked out how long it lasts.

In addition, protein mutations in the delta variant were found to significantly reduce the effect of acquired humoral immunity to COVID-19 from prior infection or vaccination.

The XBB.1 pseudovirus was 7.6 times more infectious than the BA.2 pseudovirus, as this viral RBD experienced a notable boost in pseudovirus infectivity due to two substitutions of R346T and L368I.

Programmed cell death serves as a critical defense mechanism during viral infection. The kinases RIPK1 and RIPK3, central regulators of programmed cell death pathways, undergo precise modulation ...

Moreover, the induction of a broad humoral and cellular immune response has already been demonstrated in animal models, reflecting the spectrum of antiviral immunity in humans.

However, the prevalence of natural humoral immunity, with Nabs, prevents a significant proportion of the population from being treated with AAV-based gene therapy. IgG appears to be the ...
