BackgroundEmerging studies indicate that some coronavirus disease 2019 (COVID-19) patients suffer from persistent symptoms, including breathlessness and chronic fatigue; however, the long-term immune response in these presently remains ill-defined.MethodsHere, we describe phenotypic functional characteristics of B T cells hospitalized COVID-19 during acute at 3–6 months convalescence.FindingsWe report alterations cell subsets observed were largely recovered convalescent patients. In...
Abstract Purpose: Combination of chemotherapy with programmed cell death 1 (PD-1) blockade is a front-line treatment for lung cancer. However, it remains unknown whether and how affects the response exhausted CD8 T cells to PD-1 blockade. Experimental Design: We used well-established mouse model T-cell exhaustion chronic lymphocytic choriomeningitis virus (LCMV) infection assess effect (cisplatin+pemetrexed) on blockade, in absence impact antigen release presentation observed tumor models....
Immunological memory is a defining feature of immunity, yet surprisingly there no consensus on how to quantitatively describe antibody titers wane over time. A major problem that the slow waning requires collection data for decades post-infection or vaccination. Our analysis largest existing dataset shows power-law model describes better than other frequently used models. suggests: (i) Protective levels antibodies many vaccine/virus antigens may be maintained longer previously estimated....
Passive immunization with broadly neutralizing antibodies (bNAbs) of HIV-1 appears a promising strategy for eliciting long-term remission. When administered concomitantly the cessation antiretroviral therapy (ART) to patients established viremic control, bNAb is expected prolong Surprisingly, in clinical trials on chronic patients, VRC01 failed remission substantially. Identifying cause this failure important improving VRC01-based therapies and unraveling potential vulnerabilities other...

This technical summary examines the design and violation analysis of analog virtual circuits with bilateral complementary switches. The primary consciousness is on examining electric traits operation switches from stand factors overall gate fee capacitance outcomes. To analyze impact switching parameters circuit performance, a model built to expect time-domain waveform an idealized switch. version then validated through experimental measurements three special types switches: PMOS, CMOS,...

Abstract Many vaccines against respiratory viruses have proven suboptimal in generating long-lasting sterilizing immunity and preventing transmission among populations. It is well established that tract resident memory CD8 T cells (TRM) induced by vaccination can reduce viral burdens limit immunopathology upon direct inoculation of viruses. However, the ability TRM to has remained elusive. We developed a murine model investigate role using Sendai virus, which naturally transmits mice....
Abstract Broadly neutralizing antibodies (bNAbs) of HIV-1 hold promise eliciting long-term remission. Surprisingly, the bNAb VRC01, when administered concomitantly with cessation successful antiretroviral therapy (ART), failed rapidly in chronic patients. We hypothesized that failure was due to VRC01-resistant strains were formed before ART initiation, survived latently infected cells, and reactivated during VRC01 therapy. Current assay limitations preclude testing this hypothesis...
