Multimeric nanobodies from camelid mice and llamas neutralize SARS-CoV-2 variants

Project description:Since the start of the coronavirus disease-2019 (COVID-19) pandemic, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has caused more than 2 million deaths worldwide. Many vaccines have been deployed to date; however, the continual evolution of the viral receptor binding domain (RBD) has recently challenged their efficacy. In particular, SARS-CoV-2 variants originating in South Africa (B.1.351) and the U.K. (B.1.1.7) have reduced plasma neutralization activity and crippled antibody cocktails that received emergency use authorization1-3. Whereas vaccines can be updated periodically to account for emerging variants, complementary strategies are urgently needed to overcome viral escape. One potential alternative are camelid VHHs (also known as nanobodies), which can access conserved epitopes often hidden to conventional antibodies4-6. We here isolate anti-RBD nanobodies from llamas and mice engineered to produce VHHs from alpacas, dromedaries and camels. Through neutralization assays and cryo-electron microscopy we identify two “nanomouse” VHHs that circumvent RBD antigenic drift by recognizing a domain conserved in coronaviruses, away from the ACE2 binding motif. Conversely, llama nanobodies recognize the RBD-ACE2 interphase and as monomers they are ineffective against E484K or N501Y substitutions. Notably, as homotrimers those same VHHs neutralize RBD variants with ultrahigh (pM) affinity, rivaling the most potent antibodies produced to date against SARS-CoV-2. We conclude that multivalent nanobodies can avert SARS-CoV-2 escape mutants and thus they represent promising tools to prevent COVID-19 mortality when vaccines are compromised.

Effects of plasma-derived exosomes from the normal and thin camels on hepatocellular carcinoma and their differences at transcriptome and proteomics levels

Project description:Background: Hepatocellular carcinoma (HCC) is a common malignant primary tumor. Camels have high economic and social values, but their potential medical value has not been studied. This study aimed to investigate the effects of thin and normal camel plasma-derived exosomes on HCC. Methods: Plasma was obtained from thin and normal camels, and used to isolate exosomes by ultracentrifugation. The exosomes were then characterized by transmission electron microscopy and Nano particle tracking analyzer. In vivo imaging of nude mice and hematoxylin eosin (HE) staining of liver tissues were used to explore the effects of the exosomes on tumor growth. Finally, the differences of the two exosomes were further analyzed using small RNA sequencing and proteomics. Results: In vivo imaging and HE staining showed that no significant differences were found in fluorescence value and liver tissue morphology between the control mice and the mice treated with the exosomes from thin camels; while the fluorescence value and the live histology changes were alleviated in the mice with the exosomes from normal camels. After sequencing and proteomic analysis, 40 DE-miRNAs (15 down-regulated and 25 up-regulated) and 172 DEPs (77 up-regulated and 95 down-regulated) were identified in the plasma-derived exosomes from normal camels. These identified DE-miRNAs and DEPs were significantly enriched in many signaling pathways. Conclusions: Normal camel plasma-derived exosomes may inhibit the growth of HCC cells through regulating pathways of Ras, Rap1, PI3K-Akt, MAPK, AMPK, and canonical Wnt signaling pathways.

Pulldown of human serum proteins with Trypanosoma brucei Invariant Surface Glycoprotein 75

Project description:Subspecies of Trypanosoma brucei are the causative agents of Human African Trypanosomiasis (HAT) in Sub-Saharan Africa. The surface proteome of trypanosome parasites serves a critical function at the host-parasite interface and is essential for immune evasion. Most of the surface area is covered by the variable surface glycoproteins (VGSs). Embedded within the VSGs is the protein receptor Invariant Surface Glycoprotein 75 (ISG75) with unknown function. The project aims to identify potential ligands of ISG75 in human serum.
