Yoshinori Kawabe et al.
Precise spatial restriction of transgene expression is essential for safe in vivo production of bioactive proteins; however, regulatory elements that confer tissue specificity often span large genomic regions and are incompatible with size-...
Biparatopic affibody engineering enables high-affinity sortilin blockade and progranulin elevation [0.03%]
双价AFFIBODY工程实现高亲和力SORL1阻断并升高PGRN水平
Moira Ek,Hanna Lindberg,Stefan Ståhl et al.
Moira Ek et al.
Loss-of-function mutations in the gene encoding progranulin (PGRN) are a common cause of frontotemporal dementia, leading to markedly decreased PGRN levels. A potential therapeutic strategy is therefore to increase extracellular PGRN by blo...
