What people are saying
The overall discussions show strong agreement with the article, highlighting the essential roles of TMPRSS2 and furin in viral activation, with posts praising the research, discussing inhibition methods, and emphasizing potential treatments. The tone ranges from supportive acknowledgment to detailed insights into the virus's activation pathways, underscoring both scientific consensus and the perceived importance of the findings for future therapies.
Most posts clearly express strong support and acknowledgment of the importance of TMPRSS2 and furin in SARS-CoV-2 activation, reflecting consensus.
Posts demonstrate high engagement with the topic, discussing molecular mechanisms and potential therapeutic implications.
While many discuss the study's findings in detail, some are more confirmatory or supportive rather than deeply analytical.
The discussion emphasizes the significance of these proteases as therapeutic targets, indicating a recognition of high potential impact for COVID-19 treatment strategies.
Abstract in brief
- SARS-CoV-2 enters human airway cells by using host proteases, specifically furin and TMPRSS2, to activate its spike protein by cleaving it at two key sites.
- The study shows that inhibiting TMPRSS2 and furin can significantly block virus activation and replication, with TMPRSS2 being crucial for activation in airway cells and furin also playing a role.
- Using a combination of inhibitors targeting both proteases results in stronger antiviral effects, suggesting a promising therapeutic approach for COVID-19 treatment.

@maja4185 Und die Anwesenheit von TMPRSS2, einer Protease, die in der Zellmembran sitzt, scheint die Verschmelzung des Spikeproteins mit der Zelle durch Spaltung des Spikes an einer anderen Stelle (S2') auch noch effizienter zu gestalten: https://t.co/oTfsTM2XFb

@florian_krammer @BenBCDE @NateSilver538 @DouthatNYT @sailorrooscout whether the polybasic cleavage site is retained or gradually lost from viral spike clearly depends on MOI, the composition of the host proteases and which entry pathway is used by the respective cell line (compare Vero, 293T, Calu3, Caco2…). https://t.co/rKoFVcmVwK
