Motivated by historical and present clinical observations, we discuss the possible unfavorable evolution of the immunity (similar to documented antibody-dependent enhancement scenarios) after a first infection with COVID-19. More precisely we ask the question of how the epidemic outcomes are affected ...
Ten-month immunity after Covid-19 infection seems strong against all variants of the coronavirus, the study found. 研究发现,感染新冠病毒10个月后,对所有冠状病毒变体的免疫力似乎都很强。 “There’s quite a long sustained...
Persistent antibody-dependent immunity could provide protection against circulating variants after one year, despite significantly decreased neutralizing activities against Beta, Delta and Mu variants. In conclusion, these data show that despite a marked decline in neutralizing activity over time, nAb ...
A closer look at the memory B cells revealed something surprising: these cells had gone through numerous rounds of mutation even after the infection resolved, and as a result the antibodies they produced were much more effective than the originals. Subsequent lab experiments showed this new set of...
Although health officials know that the body produces antibodies as a result of COVID-19 infection, they don't know how long the immunity those antibodies may produce will last. Will it last for a season like the common cold? This would mean that patients could contract the coronavirus multip...
Persistence of SARS-CoV-2 as an endemic virus, perhaps with seasonal epidemic peaks, may be fuelled by pockets of susceptible individuals and waning immunity after infection or vaccination, changes in the virus through antigenic drift that diminish protection and re-entries from zoonotic reservoirs. ...
本文献于2021年6月发表在美国医学学术期刊《免疫》(Immunity)上。文中美国弗莱堡大学医学院的研究人员发现,COVID-19患者的中枢神经系统可能产生了严重的炎症反应,并涉及到血管系统和大脑组织周围的多种不同免疫细胞。 在感染冠状病毒SARS-CoV-2期间和之后,患者可能会出现严重的神经系统症状,包括与COVID-19相关的味觉...
The concurrent presence of COVID-19 infection in advanced cancer patients has increased the mortality since the compromised immunity was inevitably worsen. The role and clinical impact of autologous adoptive T... Authors:Congcong Li, Dazhao Xu, Linyao Lu, Shu Peng, Haiyang Zhao, Chuxiong Zeng,...
The dynamics, duration, and nature of immunity produced during SARS-CoV-2 infection are still unclear. Here, we longitudinally measured virus-neutralising antibody, specific antibodies against the spike (S) protein, receptor-binding domain (RBD), and the
同时,有COVID-19病史的人应该意识到,在短期内他们出现过敏表现的风险较高。New study reveals increased risk of allergic diseases after COVID-19 infectionA recent study published in Nature Communications explored the association of COVID-19 with long-term allergic conditions....
