Diverse Functional Autoantibodies in Patients with COVID-19 | Nature
▻https://www.nature.com/articles/s41586-021-03631-y
We found that #COVID-19 patients exhibit dramatic increases in autoantibody reactivities compared to uninfected controls, with a high prevalence of autoantibodies against immunomodulatory proteins including cytokines, chemokines, complement components, and cell surface proteins. We established that these autoantibodies perturb immune function and impair virological control by inhibiting immunoreceptor signaling and by altering peripheral immune cell composition, and found that murine surrogates of these autoantibodies exacerbate disease severity in a mouse model of #SARS-CoV-2 infection. Analysis of autoantibodies against tissue-associated antigens revealed associations with specific clinical characteristics and disease severity. In summary, these findings implicate a pathological role for exoproteome-directed autoantibodies in COVID-19 with diverse impacts on immune functionality and associations with clinical outcomes.
How One Firm Drove Influence Campaigns Nationwide for Big Oil
▻https://www.nytimes.com/2020/11/11/climate/fti-consulting.html
FTI, a global consulting firm, helped design, staff and run organizations and websites funded by energy companies that can appear to represent grass-roots support for fossil-fuel initiatives.
In early 2017, the Texans for Natural Gas website went live to urge voters to “thank a roughneck” and support fracking. Around the same time, the Arctic Energy Center ramped up its advocacy for drilling in Alaskan waters and in a vast Arctic wildlife refuge. The next year, the Main Street Investors Coalition warned that climate activism doesn’t help mom-and-pop investors in the stock market.
All three appeared to be separate efforts to amplify local voices or speak up for regular people.
On closer look, however, the groups had something in common: They were part of a network of corporate influence campaigns designed, staffed and at times run by FTI Consulting, which had been hired by some of the largest oil and gas companies in the world to help them promote fossil fuels.
