Polymer-protein conjugates are biohybrid macromolecules derived from covalently connecting synthetic polymers with polypeptides. The resulting materials combine the properties of both worlds: chemists can engineer polymers to stabilize proteins, to add functionality, or to enhance activity; whereas biochemists can exploit the specificity and complexity that Nature has bestowed upon its macromolecules. This has led to a wealth of applications, particularly within the realm of biomedicine. Polymer-protein conjugation has expanded to include scaffolds for drug delivery, tissue engineering, and microbial inhibitors. This feature article reflects upon recent developments in the field and discusses the applications of these hybrids from a biomaterials standpoint.

Therapeutic proteins are commonly conjugated with polymers to modulate their pharmacokinetics but often lack a description of the polymer-protein interaction. We deployed limited proteolysis mass spectrometry (LiP-MS) to reveal the interaction of polyethylene glycol (PEG) and PEG alternative polymers with interferon-α2a (IFN). Target conjugates were digested with the specific protease trypsin and a "heavy" N-IFN wild type (IFN-WT) for time-resolved quantification of the cleavage dynamics.

Polymer-drug conjugates and polymer-protein conjugates have been pivotal in the realm of drug delivery systems for over half a century. These polymeric drugs are characterized by the conjugation of therapeutic molecules or functional moieties to polymers, enabling a range of benefits including extended circulation times, targeted delivery, controlled release, and decreased immunogenicity. This review delves into recent advancements and challenges in the clinical translations and preclinical studies of polymer-drug conjugates and polymer-protein conjugates.

Polymeric nanoparticles (NPs) comprised of poly(lactic-co-glycolic acid) (PLGA) have found success in modulating antigen (Ag)-specific T cell responses for the treatment multiple immunological diseases. Common methods by which Ags are associated with NPs are through encapsulation and surface conjugation; however, these methods suffer from several limitations, including uncontrolled Ag loading, burst release, and potential immune recognition. To overcome these limitations and study the relationship between NP design parameters and modulation of innate and Ag-specific adaptive immune cell responses, we developed ovalbumin (OVA) protein-PLGA bioconjugate NPs (acNP-OVA).

Article Synopsis
- Bioconjugation of polymers to proteins can enhance the stability and effectiveness of biologic systems, but the impact of different polymer structures is not fully understood.
- This study focuses on the first bioconjugation of a cyclic polymer, specifically poly(ethylene glycol), to a model protein (T4 lysozyme) to explore its unique properties.
- By comparing the cyclic polymer-protein conjugate with a linear version and using molecular dynamics simulations, the research aims to highlight the potential of cyclic polymers in improving therapeutic applications.

Protein-polymer conjugates combine the unique properties of both proteins and synthetic polymers, making them important materials for biomedical applications. In this work, we synthesized and characterized protein-branched polymer bioconjugates that were precisely designed to retain protein functionality while preventing unwanted interactions. Using chymotrypsin as a model protein, we employed a controlled radical branching polymerization (CRBP) technique utilizing a water-soluble inibramer, sodium 2-bromoacrylate.
