Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) poses a public health threat for which preventive and therapeutic agents are urgently needed. Neutralizing antibodies key class of therapeutics that may bridge widespread vaccination campaigns offer treatment solution in populations less responsive to vaccination. Here, we report high-throughput microfluidic screening antigen-specific B cells led the identification LY-CoV555 (also known as bamlanivimab), potent anti-spike...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-neutralizing monoclonal antibodies (mAbs) can reduce the risk of hospitalization from disease 2019 (COVID-19) when administered early. However, SARS-CoV-2 variants concern (VOCs) have negatively affected therapeutic use some authorized mAbs. Using a high-throughput B cell screening pipeline, we isolated LY-CoV1404 (bebtelovimab), highly potent spike glycoprotein receptor binding domain (RBD)-specific antibody. potently neutralizes...
SARS-CoV-2 poses a public health threat for which therapeutic agents are urgently needed. Herein, we report that high-throughput microfluidic screening of antigen-specific B-cells led to the identification LY-CoV555, potent anti-spike neutralizing antibody from convalescent COVID-19 patient. Biochemical, structural, and functional characterization revealed high-affinity binding receptor-binding domain, ACE2 inhibition, activity. In rhesus macaque challenge model, prophylaxis doses as low 2.5...
BACKGROUND Bebtelovimab is a potent, fully human IgG1 monoclonal antibody (mAb) targeting the S-protein of SARS-CoV-2, with broad neutralizing activity to all currently known SARS-CoV-2 variants concern, including omicron variant lineages.

Catabolite repression of a number catabolic operons in bacilli is mediated by the catabolite control protein CcpA, phosphocarrier HPr from phosphoenolpyruvate-dependent sugar transport system (PTS), and cis-acting DNA sequence termed catabolite-responsive element (cre). We present evidence that CcpA interacts with phosphorylated at Ser46 (Ser(P) HPr) these proteins form specific ternary complex cre DNA. Titration experiments following circular dichroism signal indicate this consists two...
Altered coagulation and inflammation contribute to the pathogenesis of ischemic renal injury. Thrombomodulin is a necessary factor in anticoagulant protein C pathway has inherent anti-inflammatory properties. We studied effect soluble thrombomodulin (sTM) hypoperfusion model kidney To markedly reduce infrarenal aortic blood flow femoral arterial pressures, we clamped suprarenal aorta rats, occluding them 90%, for 60 min. Reversible acute injury (AKI) occurred at 24 h rats subjected...

We describe a bispecific dual-antagonist antibody against human B cell activating factor (BAFF) and interleukin 17A (IL-17). An anti-IL-17 single-chain variable fragment (scFv) derived from ixekizumab (Taltz®) was fused via glycine-rich linker to anti-BAFF tabalumab. The IgG-scFv bound both BAFF IL-17 simultaneously with identical stoichiometry as the parental mAbs. Stability studies of initial revealed chemical degradation aggregation not observed in either antibody. scFv showed high...
Abstract The kinetic folding mechanism for Escherichia coli dihydrofolate reductase postulates two distinct types of transient intermediates. first forms within 5 ms and has substantial secondary structure but little stability. second is a set four species that appear over the course several hundred milliseconds have structure, specific tertiary significant stability (Jennings PA, Finn BE, Jones Matthews CR, 1993, Biochemistry 52 :3783–3789).

Administration of activated protein C (APC) protects from renal dysfunction, but the underlying mechanism is unknown. APC exerts both antithrombotic and cytoprotective properties, latter via modulation protease-activated receptor-1 (PAR-1) signaling. We generated variants to study relative importance two functions in a model LPS-induced microvascular dysfunction. Compared with wild-type APC, K193E variant exhibited impaired anticoagulant activity retained ability mediate PAR-1-dependent In...
Poor solubility is a common challenge encountered during the development of high concentration monoclonal antibody (mAb) formulations, but there are currently no methods that can provide predictive information on high-concentration behavior mAbs in early discovery. We explored utility methodologies used for determining extrapolated as way to rank-order based their relative properties. devised two approaches accomplish this: 1) vapor diffusion technique utilized traditional protein...

Human activated protein C (APC) is an antithrombotic, antiinflammatory serine protease that plays a central role in vascular homeostasis, and recombinant C, drotrecogin alfa (activated), has been shown to reduce mortality patients with severe sepsis. Similar other proteases, functional APC levels are regulated by the inhibitor family of proteins including α 1 -antitrypsin inhibitor. Using APC–substrate modeling, we designed produced number derivatives goal altering proteolytic specificity...
