Is unique bioactive polyphenolic profile of guava ( Psidium guajava ) budding leaf tea related to plant biochemistry of budding leaves in early dawn?
We have successfully developed a new process for manufacturing GLTSF with a unique polyphenolic profile. Such characteristic compositional distribution can be ascribed to the right harvesting hour in the early dawn and appropriate treatment process at low temperature, avoiding direct sunlight.
Our results specifically implicate antigen and not inflammation in driving activation of apoptotic mechanisms without cell death in proliferating CD8(+) T cells. Furthermore, the contraction of CD8(+) T cell response following expansion is likely not mediated by the key downstream apoptosis inducer, caspase-3.
