Sir Humphrey Appleby, the Machiavellian senior civil servant in the hit 1980s British sitcom Yes, Minister once famously commented that one should “never believe anything until it’s been officially denied.” Which meant we could be fairly confident that racial and ethnic differences in susceptibility to Coronavirus exist, because our race-denying Ruling Class so dogmatically refused to consider the evidence. Now that’s over: a study by a Chinese research group has emerged that offers concrete proof of race differences in susceptibility to Corona virus are very real.
The study—a preprint that has not yet been peer-reviewed—is entitled Single-cell RNA expression profiling of ACE2, the putative receptor of Wuhan 2019-nCov, By Yu Zhao et al., bioRxiv, 2020] and is authored by a group of medical scientists based at Tongji University in Shanghai
The authors explain that “2019-nCov was reported to share the same receptor, Angiotensin-converting enzyme 2 (ACE2)” as the SARS disease, an outbreak of which in 2003 seemed almost exclusively to kill Northeast Asians.
Based on “the public database and the state-of-the-art single-cell RNA-Seq technique” the Chinese scientists “analyzed the ACE2 RNA expression profile in the normal human lungs.” Crucially, they further found (in a comparison of eight individual samples) that the “Asian male one has an extremely large number of ACE2-expressing cells in the lung” in comparison to other races. (The database was based on analysis of eight normal human lung transplant donors of different races.)
