Mediation Analyses for the Effect of Antibodies in Vaccination [PDF]
Journal of Causal Inference, 2024, 12:20220043, 2022 We review standard mediation assumptions as they apply to identifying antibody effects in a randomized vaccine trial and propose new study designs to allow identification of an estimand that was previously unidentifiable. For these mediation analyses, we partition the total ratio effect (one minus the vaccine effect) from a randomized vaccine trial ...

Using cluster theory to calculate the experimental structure factors of antibody solutions [PDF]
, 2022 Monoclonal antibody solutions are set to become a major therapeutic tool in the years to come, capable of targeting various diseases by clever designing their antigen binding site. However, the formulation of stable solutions suitable for patient self-administration typically presents challenges, as a result of the increase in viscosity that often ...

Antibody binding reports spatial heterogeneities in cell membrane organization [PDF]
, 2022 The spatial organization of cell membrane glycoproteins and glycolipids is critical for mediating the binding of ligands, receptors, and macromolecules on the plasma membrane. However, we currently do not have the methods to quantify the spatial heterogeneities of macromolecular crowding on live cell surfaces.

Modelling Bi-specific Antibodies in Aqueous Solution [PDF]
arXiv, 2023 This study presents theoretical results for physico-chemical properties of system of molecules modeling bi-specific antibodies, such as, dual-variable-domain monoclonal antibodies (DVD-Ig) and Fabs-In-Tandem Immunoglobulin (FIT-Ig). These molecules are representatives of the engineered proteins that combine the function and specificity of two ...

Behaviour of the model antibody fluid constrained by rigid spherical obstacles. Effects of the obstacle--antibody attraction [PDF]
arXiv, 2021 This study is concerned with behaviour of fluid of monoclonal antibodies (mAbs) when trapped in a confinement represented by rigid spherical obstacles that attract proteins. The antibody molecule is depicted as an assembly of seven hard spheres, organized to resemble Y shaped molecule.

arXiv, 2020 Thermodynamic profiles, based on bioinformatic hydropathicity scales and membrane-fitted sliding windows, exhibit accurately level sets of hydrophobic peaks or valleys in the constant fragment Fc of monoclonal antibodies. These sets provide a roadmap for selected short regions where a few directed amino acid mutations could produce either accelerated ...

Omicron (B.1.1.529): Infectivity, vaccine breakthrough, and antibody resistance [PDF]
arXiv, 2021 The latest severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant Omicron (B.1.1.529) has ushered panic responses around the world due to its contagious and vaccine escape mutations. The essential infectivity and antibody resistance of the SARS-CoV-2 variant are determined by its mutations on the spike (S) protein receptor-binding domain (

Substantial Doubt Remains about the Efficacy of Anti-Amyloid Antibodies [PDF]
arXiv, 2023 Alzheimer's disease (AD) is a prevalent, progressive, and ultimately fatal neurodegenerative disorder that is defined pathologically by the accumulation of amyloid plaques and tau neurofibrillary tangles in the brain. There remains an unmet need for therapies that can halt or slow the course of AD. To address this need, the FDA has provided a mechanism,

Dynamic Optimization for Monoclonal Antibody Production [PDF]
arXiv, 2023 This paper presents a dynamic optimization numerical case study for Monoclonal Antibody (mAb) production. The fermentation is conducted in a continuous perfusion reactor. We represent the existing model in terms of a general modeling methodology well-suited for simulation and optimization. The model consists of six ordinary differential equations (ODEs)

How is the Monoclonal Antibodies Kinetic Affected by Changes of Their Physical Parameters? [PDF]
arXiv, 2010 The study of monoclonal antibodies (MAb) is a field of great interest to science medicine, for example, anti-TNF agents (infliximab and adalimumab) represent an important tool for the management of autoimmune and inflammatory disorders. In this work we focus on the physical description of the transport kinetics of MAb in a fluid with laminar flow and ...
