Abstract
The formation of inclusion bodies (IBs) during expression of recombinant therapeutic proteins using E. coli is a significant hurdle in producing high-quality, safe, and efficacious medicines. The improved understanding of the structure-function relationship of the IBs has resulted in the development of novel biotechnologies that have streamlined the isolation, solubilization, refolding, and purification of the active functional proteins from the bacterial IBs. Together, this overall effort promises to radically improve the scope of experimental biology of therapeutic protein production and expand new prospects in IBs usage. Notably, the IBs are increasingly used for applications in more pristine areas such as drug delivery and material sciences. In this review, we intend to provide a comprehensive picture of the bio-processing of bacterial IBs, including assessing critical gaps that still need to be addressed and potential solutions to overcome them. We expect this review to be a useful resource for those working in the area of protein refolding and therapeutic protein production.

Abstract
Inclusion bodies (IBs) are large, insoluble aggregates that often form during the overexpression of proteins in bacteria. These aggregates are of broad fundamental and practical significance, for recombinant protein preparation and due to their relevance to aggregation-related medical conditions and their recent emergence as promising functional nanomaterials. Despite their significance, high resolution knowledge of IB structure remains very limited. Such knowledge will advance understanding and control of IB formation and properties in myriad practical applications. Here, we report a detailed quenched hydrogen-deuterium amide exchange (qHDX) method with NMR readout to define the structure of IBs at the level of individual residues throughout the protein. Applying proper control of experimental conditions, such as sample pH, water content, temperature, and intrinsic rate of amide exchange, yields in depth results for these cellular protein aggregates. qHDX results illustrated for Cu, Zn superoxide dismutase 1 (SOD1) and Adnectins show their IBs include native-like structure and some but not all mutations alter IB structure.

The Poly-Histidine Tag H6 Mediates Structural and Functional Properties of Disintegrating, Protein-Releasing Inclusion Bodies. Pharmaceutics 2022; 14:pharmaceutics14030602. [PMID: 35335976 PMCID: PMC8955739 DOI: 10.3390/pharmaceutics14030602] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 03/04/2022] [Accepted: 03/07/2022] [Indexed: 12/13/2022] Open
Abstract
The coordination between histidine-rich peptides and divalent cations supports the formation of nano- and micro-scale protein biomaterials, including toxic and non-toxic functional amyloids, which can be adapted as drug delivery systems. Among them, inclusion bodies (IBs) formed in recombinant bacteria have shown promise as protein depots for time-sustained protein release. We have demonstrated here that the hexahistidine (H6) tag, fused to recombinant proteins, impacts both on the formation of bacterial IBs and on the conformation of the IB-forming protein, which shows a higher content of cross-beta intermolecular interactions in H6-tagged versions. Additionally, the addition of EDTA during the spontaneous disintegration of isolated IBs largely affects the protein leakage rate, again protein release being stimulated in His-tagged materials. This event depends on the number of His residues but irrespective of the location of the tag in the protein, as it occurs in either C-tagged or N-tagged proteins. The architectonic role of H6 in the formation of bacterial IBs, probably through coordination with divalent cations, offers an easy approach to manipulate protein leakage and to tailor the applicability of this material as a secretory amyloidal depot in different biomedical interfaces. In addition, the findings also offer a model to finely investigate, in a simple set-up, the mechanics of protein release from functional secretory amyloids.

Abstract
Nanostructures decorated with antibodies (Abs) are applied in bioimaging and therapeutics. However, most covalent conjugation strategies affect Abs functionality. In this study, we aimed to create protein-based nanoparticles to which intact Abs can be attached through tight, specific, and noncovalent interactions. Initially considered waste products, bacterial inclusion bodies (IBs) have been used in biotechnology and biomedicine. However, the amyloid-like nature of IBs limits their functionality and raises safety concerns. To bypass these obstacles, we have recently developed highly functional α-helix-rich IBs exploiting the natural self-assembly capacity of coiled-coil domains. We used this approach to create spherical, submicrometric, biocompatible and fluorescent protein nanoparticles capable of capturing Abs with high affinity. We showed that these IBs can be exploited for Ab-directed cell targeting. Simultaneous decoration of the nanoparticles with two different Abs in a controllable ratio enabled the construction of a bispecific antibody mimic that redirected T lymphocytes specifically to cancer cells. Overall, we describe an easy and cost-effective strategy to produce multivalent, traceable protein nanostructures with the potential to be used for biomedical applications. STATEMENT OF SIGNIFICANCE: Functional inclusion bodies (IBs) are promising platforms for biomedical and biotechnological applications. These nanoparticles are usually sustained by amyloid-like interactions, which imposes some limitations on their use. In this work, we exploit the natural coiled-coil self-assembly properties to create highly functional, nonamyloid, and fluorescent IBs capable of capturing antibodies. These protein-based nanoparticles are successfully used to specifically and simultaneously target two unrelated cell types and bring them close together, becoming a technology with potential application in bioimaging and immunotherapy.

Abstract
The clinically successful adjuvant MF59 is used in seasonal influenza vaccines, which is proposed to enhance immunity by creating an immune-competent microenvironment in the muscle that allows recruitment of immune cells that drive adaptive immune responses. Here, we examined whether the clinically successful adjuvants MF59/AddaVax could be used for subcutaneous use and how antigen delivery can be synergized with cellular dynamics at the vaccination site. Subcutaneous injection of AddaVax leads to thickening of the skin, characterized by a neutrophil-monocyte recruitment sequence. Skin-infiltrating CCR2+Ly6Chigh monocytes showed differentiation to CD11b+Ly6C+MHCII+CD11c+CD64+ monocyte-derived DCs over time in the hypodermal layers of the skin, expressing high levels of CD209a/mDC-SIGN. Surprisingly, skin thickening was accompanied with increased white adipose tissue highly enriched with monocytes. Analysis of the skin-draining lymph nodes revealed early increases in neutrophils and moDCs at 12 hours after injection and later increases in migratory cDC2s. Subcutaneous vaccination with AddaVax enhanced antigen-specific CD8+ and CD4+ T cell responses, while moDC targeting using antigen-coupled CD209a antibody additionally boosted humoral responses. Hence, oil-in-water emulsions provide an attractive immune modulatory adjuvants aimed at increasing cellular responses, as well as antibody responses when combined with moDC targeting.
