Experimental Data and PBPK Modeling Quantify Antibody Interference in PEGylated Drug Carrier Delivery
BULLETIN OF MATHEMATICAL BIOLOGY, 83(12).
author keywords: PBPK model; Latin hypercube sampling; Parameter optimization; Anti-PEG antibodies; PEGylated liposomes
MeSH headings : Animals; Drug Carriers; Mathematical Concepts; Mice; Models, Biological; Polyethylene Glycols / pharmacokinetics; Positron Emission Tomography Computed Tomography; Tissue Distribution
TL;DR:
Near-continuous experimental measurements of PL concentration during the first hour post-injection from the liver, spleen, kidney, muscle, lung, and blood plasma, are used as truth sets with LHS to infer optimal parameter ranges for the full PBPK model.

LPS-binding IgG arrests actively motile Salmonella Typhimurium in gastrointestinal mucus
MUCOSAL IMMUNOLOGY, 13(5), 814–823.
MeSH headings : Animals; Antibodies, Bacterial / immunology; Disease Models, Animal; Immunoglobulin Fab Fragments / immunology; Immunoglobulin Fc Fragments / immunology; Immunoglobulin G / immunology; Intestinal Mucosa; Lipopolysaccharides / immunology; Mice; Mucus / immunology; Mucus / microbiology; Polysaccharides / immunology; Protein Binding / immunology; Salmonella Infections / immunology; Salmonella Infections / microbiology; Salmonella typhimurium / immunology
TL;DR:
The addition of anti-lipopolysaccharide IgG to GI mucus markedly reduced the progressive motility of Salmonella by lowering the swim speed and retaining individual bacteria in an undirected motion state, implicate IgG-mucin crosslinking as a broadly conserved function that reduces mucous penetration of both bacterial and viral pathogens.

Modeling the Mechanisms by Which Coexisting Biomolecular RNA-Protein Condensates Form
BULLETIN OF MATHEMATICAL BIOLOGY, 82(12).
author keywords: Liquid– liquid phase separation; Flory– Huggins; RNA– protein dynamics; Phase field model
MeSH headings : Biophysical Phenomena; Kinetics; Mathematical Concepts; Models, Biological; Proteins / metabolism; RNA / metabolism
TL;DR:
This work presents a mathematical model to examine molecular mechanisms that yield phase-separated droplets composed of different RNA–protein complexes using a Cahn–Hilliard diffuse interface model with a Flory–Huggins free energy scheme to explore how multiple protein–RNA complexes can establish a heterogeneous droplet field.

Partial demixing of RNA-protein complexes leads to intradroplet patterning in phase-separated biological condensates
PHYSICAL REVIEW E, 99(1).
MeSH headings : Kinetics; Models, Biological; RNA / metabolism; RNA-Binding Proteins / metabolism
TL;DR:
This study illustrates that spatiotemporal heterogeneity can emerge within phase-separated biological condensates with simple binding reactions and competition and demonstrates that intradroplet patterning may influence droplet composition and, subsequently, cellular organization on a larger scale.
