T13 |
0-233 |
Sentence |
denotes |
Treatment of Covid-19 urges a deeper understanding of the underlying molecular mechanisms involved in disease progression to provide a prompt therapeutical response with an adequate use of available drugs, including drug repurposing. |
T14 |
234-355 |
Sentence |
denotes |
Indeed, there is a number of ongoing clinical trials to test the efficacy of diverse FDA-approved drugs against Covid-19. |
T15 |
356-502 |
Sentence |
denotes |
Among them, a few involve assessment of the therapeutic efficacy of IL-6 inhibition, unfortunately without reporting conclusive results [9,10,11]. |
T16 |
503-672 |
Sentence |
denotes |
Recently, it was proposed that dysregulated bradykinin (BK) signaling could be the trigger of the cytokine storm observed in patients with severe Covid-19 [12,13,14,15]. |
T17 |
673-908 |
Sentence |
denotes |
The rational for this hypothesis relies on the increased availability of BK and its metabolite des-Arg9-BK in Covid-19 patients, due to the downregulation of angiotensin converting enzyme 2 (ACE2), the entry protein of SARS-Cov-2 [16]. |
T18 |
909-1090 |
Sentence |
denotes |
Indeed, ACE2 downregulation increases the amount of angiotensin I processed by the angiotensin-converting enzyme (ACE) with a concomitant decrease of its degradation activity on BK. |
T19 |
1091-1227 |
Sentence |
denotes |
Moreover, levels of des-Arg9-BK are also increased due to the diminished degradative activity of ACE2 caused by its downregulation [12]. |
T20 |
1228-1328 |
Sentence |
denotes |
The BK hypothesis is consistent with the observed elevated levels of IL-6 in Covid-19 patients [17]. |
T21 |
1329-1466 |
Sentence |
denotes |
This new perspective suggests that inhibition of BK signaling may be a suitable therapy to avoid the cytokine storm and its consequences. |
T22 |
1467-1679 |
Sentence |
denotes |
Indeed, as a proof of principle, preliminary results from a limited study suggests that inhibition of the BK signaling is associated with a decrease of the oxygen supplementation needed by Covid-19 patients [18]. |
