Recently, we published the concluding part III of the #SPIRAL model, which we were working on since 2016.

Pathological T Helper Polarization Requires Pre-existing Cross-Reactive Memory T Cells

I'm going to explain the significance of this model.

preprints.org/manuscript/202…
In part I published in 2018, we introduced the SPIRAL model. It proposes that cross-reactivity is the basic unit that drives the evolution of adaptive immune system and it is thymus-derived regulatory T cells, Tregs, that rely on cross-reactive epitopes to control other T cells
We also proposed that thymus-derived #Foxp3 Tregs rely on #CrossReactive epitope derived from the friendly gut microbiota to survive and function in the periphery. So one of the main roles of gut microflora is to supply #Tregs with epitopes.

In this study, we have developed a fast and cost-effective method
for reverse genetics of coronaviruses by combining two approaches developed by others..As the genomes can be divided into multiple short fragments, mutations can be introduced into individual
fragments easily. ImageImageImageImage
