The reason why COVID-19 patients experience innate immunosuppression at the early stage of SARS-CoV-2 infection is unclear. Wu et al. report that ORF9b accumulates immediately during SARS-CoV-2 infection and antagonizes the RIG-I-MAVS antiviral type I interferon response by interrupting the K63-linked polyubiquitination of the interferon signaling ...

Sawyer et al. use ribosome profiling to characterize the translational landscape of Mycobacterium tuberculosis . They find widespread translation of non-canonical transcripts lacking canonical bacterial translation signals. Ribosome positioning reveals differences in initiation mechanisms, and factors that stabilize intact ribosomes may ensure cont...

In this article, Hu et al. show the importance, for gene regulation, of a genomic region harboring GWAS variants that affect type 2 diabetes risk at the STARD10 locus. They also identify FCHSD2 as a likely mediator of the effects of these variants on insulin secretion.

Lu et al. predict and validate B cell epitopes on the spike (S), envelope (E), membrane (M), and nucleocapsid (N) proteins of SARS-CoV-2 using structure-based approaches. The immunodominant epitopes vary between D614 and G614 SARS-CoV-2. The epitopes on the S protein elicit neutralizing antibodies against D614 and G614 SARS-CoV-2.

Mammalians use the kynurenine pathway for tryptophan degradation inducing tolerogenic immune responses. Zelante et al. report that similarly, the fungus Aspergillus fumigatus uses the kynurenine pathway. Pathogenic immune response occurs when the fungus catabolizes tryptophan via the indolepyruvate pathway, which targets host AhR. Administration of...

Bates et al. extensively examine the cross-reactivity of selected monoclonal antibodies raised against SARS-CoV structural proteins with SARS-CoV-2. Although most SARS-CoV antibodies display remarkable cross-reactivity toward SARS-CoV-2 proteins, the spike antibodies of SARS-CoV show minimal cross-neutralization of live SARS-CoV-2 virus.

Tan et al. longitudinally analyzed the virological and immunological parameters in COVID-19 patients from disease onset until resolution or death. Early induction of functional SARS-CoV-2-specific T cells was observed in patients with mild disease and rapid viral clearance. This supports the prognostic value of detecting SARS-CoV-2-specific T cells...

Weberling and Zernicka-Goetz characterize the remodeling of the mouse epiblast upon implantation. Its transformation from oval to cup shaped is driven by the polar trophectoderm tissue. Comparative analyses with human embryos and inhibitor treatments suggest the polar trophectoderm as an evolutionarily conserved regulator of epiblast shape upon imp...
