The decarboxylation of naturally abundant amino acids, followed by subsequent inter- or intramolecular reaction cascades, enables the rapid synthesis of a variety of diverse and high-value amine derivatives. Previous methods have relied heavily on transition metals, involved tedious procedures, or required harsh conditions. Herein, we present a novel reaction cascade for the decarboxylation and nucleophilic functionalization of α-amino acids. This method is characterized by being transition-metal-free, convenient to operate, environmentally friendly and having mild conditions.

RETREG1/FAM134B is known for its role as a reticulophagy receptor. Our previous study established that RETREG1 is upregulated in hepatocellular carcinoma (HCC) and contributes to disease progression by activating the AKT signaling pathway. However, the specific mechanisms underlying the elevated expression of RETREG1 in HCC remain unclear.

TLR (Toll-like receptor)-21 is a non-mammalian TLR and exhibits a unique function within the innate immune systems of fishes, birds, and amphibians. Despite its important role as PRR (pattern recognition receptor), research on TLR21 in many fish species, as well as in rohu (Labeo rohita), remains relatively limited. This article describes the molecular cloning of LrTLR21 (TLR21 in L.

Rabies virus causes an estimated 59,000 annual fatalities worldwide and promising therapeutic treatments are necessary to develop. In this study, affinity tag-purification mass spectrometry was employed to delineate RABV glycoprotein and host protein interactions, and PDIA3/ERP57 was identified as a potential inhibitor of RABV infection. PDIA3 restricted RABV infection with follow mechanisms: PDIA3 mediated the degradation of RABV G protein by targeting lysine 332 via the selective macroautophagy/autophagy pathway; The PDIA3 interactor, AP3B1 (adaptor related protein complex 3 subunit beta 1) was indispensable in PDIA3-triggered selective degradation of the G protein; Furthermore, PDIA3 competitively bound with NCAM1/NCAM (neural cell adhesion molecule 1) to block RABV G, hindering viral entry into host cells.
