Effects on ALS
Pu-erh tea may have beneficial health effects, including preventing the onset of FET family protein-associated neurodegenerative diseases and delaying the progression of ALS by inhibiting the cytoplasmic aggregation of FET family proteins.
FET family proteins consist of fused in sarcoma/translocated in liposarcoma (FUS/TLS), Ewing's sarcoma (EWS), and TATA-binding protein-associated factor 15 (TAF15). Mutations in the copper/zinc superoxide dismutase (SOD1), TAR DNA-binding protein 43 (TDP-43), and FET family proteins are associated with the development of ALS.[1]

Sialic acid-alpha 2,6Gal-specific clones of A/duck/Ukraine/1/63 revert to sialic acid-alpha 2,3Gal-specific wild type in ovo. J. Biol. Chem. 1985;260:7362-7. PMID: 3997874. Human and animal influenza A isolates of the H3 serotype preferentially bind SA alpha 2,6Gal or SA alpha 2,3Gal linkages (where SA represents sialic acid), respectively, on cell-surface sialyloligosaccharides. Previously, we have demonstrated selection of SA alpha 2,3Gal-specific receptor variants of several human viruses which differed from the parent viruses by a single amino acid at residue 226 of the hemagglutinin which is located in the receptor binding pocket (Rogers, G. N., Paulson, J.C., Daniels, R.S., Skehel, J.J., Wilson, I.A., and Wiley, D.C. (1983) Nature 304, 76-78). In this report, the selection in the reverse direction was accomplished starting with a SA alpha 2,3Gal-specific avian virus, A/duck/Ukraine/1/63 (H3N7), yielding SA alpha 2,6Gal-specific variants that exhibit the receptor binding properties characteristic of the human isolates. Selection was again mediated at residue 226 of the hemagglutinin, in this case changing from Gln in the parent virus to Leu in the variants. Although the SA alpha 2,6Gal-specific avian virus variants were stable to passage in MDCK cells, they exhibited dramatic reversion to the SA alpha 2,3Gal-specific phenotype of the parent virus during a single passage in chicken embryos. This was in contrast to the SA alpha 2,6Gal-specific human virus isolates which were stable to passage in both hosts. The reversion of the avian virus variants in eggs provides compelling evidence for host-mediated selection of influenza virus receptor variants.
