Selective pressures have given rise to a number of SARS-CoV-2 variants during the prolonged course of the COVID-19 pandemic. Recently evolved variants differ from ancestors in additional glycosylation within the spike protein receptor-binding domain(RBD). Details of how the acquisition of glycosylation impacts viral fitness and human adaptation are not clearly understood. Here, we dissected the role of N354-linked glycosylation, acquired by BA.2.86 sub-lineages, as a RBD conformational control element in attenuating viral infectivity. The reduced infectivity is recovered in the presence of heparin sulfate, which targets the‘N354 pocket’ to ease restrictions of conformational transition resulting in a ‘RBD-up’ state, thereby conferring an adjustable infectivity. Furthermore, N354 glycosylation improved spike cleavage and cell–cell fusion, and in particular escaped one subset of ADCC antibodies. Together with reduced immunogenicity in hybrid immunity background, these indicate a single spike amino acid glycosylation event provides selective advantage in humans through multiple mechanisms.

Bacterial family Christensenellaceae performed high heritability and associated with human health status. Numerous studies observed that the abundance of Christensenellaceae could be significantly reduced in patients with intestinal diseases or metabolic disorders， inferred that it may be treated as an effective biomarker. Christensenella minuta (C. minuta) was the first member of Christensenellaceae family isolated from human fecal samples. Accumulating evidences suggested that C. minuta may demonstrate a positive bio-therapeutic effects toward unhealthy status. Hence， this review aimed to systematically summarize the characterization of Christensenellaceae under specific health or diseases， and discover its promising application. Besides， the latest studies on the pharmacological research of C. minuta also summarized. Current important literatures grasped the potential health benefits of C. minuta in managing metabolic disorders， gut ecosystem， and inflammation. Whereas， several critical knowledge gaps about the safe and clinical application remain should be addressed in future verification. C. minuta is worthy to be elevated as the next prospective probiotic star in nutraceutical or medical field and should not be overlooked.
