We conducted a pilot study using a passive radio-wave-based home monitor in individuals with Parkinson disease (PD) with a focus on gait, home activity, and time in bed. We enrolled 7 ambulatory individuals to have the device installed in the bedroom of their homes over 8 weeks and performed standard PD assessments at baseline. We evaluated the abi...

Using an infection-permissive human kidney cell line, Yeung et al. show that a soluble form of ACE2 that is cleaved and liberated from the host cell surface mediates SARS-CoV-2 binding and uptake by receptors involved in renin-angiotensin system signaling.

Structure-function analysis of the SARS-CoV-2 variant B.1.351 using serum samples from convalescent and vaccinated individuals reveals how mutations in the viral spike protein result in tighter binding to the receptor ACE2 and allow escape from monoclonal antibody neutralization.
Published in Cell
Extremely potent neutralizing human monoclonal antibodies, though rare, are isolated from COVID-19 convalescent patients and suitable for prophylactic and therapeutic interventions of wild-type SARS-CoV-2 as well as emerging variants.

Experiments with pseudotyped viruses show that the 501Y.V2 variant of SARS-CoV-2 exhibits resistance to neutralization from monoclonal antibodies and sera from convalescent as well as immunized individuals, predominantly due to the E484K and N501Y mutations in the receptor-binding domain of the viral spike protein.

Zhang et al. develop a trans- complementation system to produce single-round infectious SARS-CoV-2 that recapitulates authentic viral infection and replication. They then show the system can be safely used at biosafety level 2 for high-throughput antiviral testing.

Dejnirattisai et al. present an in-depth study of the human antibody response to SARS-CoV-2 infection. By characterizing 377 human mAbs from recovered COVID-19 patients, and determining 19 protein structures, they construct a map of antibody footprints on the RBD describe in great detail its antigenic anatomy.

The SARS-CoV-2 B.1.1.7 variant is not neutralized as easily as the original form of the virus. Some public antibodies cannot neutralize B.1.1.7, due to altered light chain contacts with residue 501. However, B.1.1.7 does not show widespread escape from monoclonal antibodies, natural antibody responses, or vaccines.

Visualization of nuclear translocation of HIV-1 capsids by 3D correlative fluorescence light and electron microscope, combined with cryoelectron tomography, demonstrates that nuclear pore complexes in infected T cells are sufficiently dilated to allow cone-shaped HIV-1 capsids to pass through.
