Asar M, Newton-Northup J, Soendergaard M. Improving Pharmacokinetics of Peptides Using Phage Display. Viruses 2024; 16:570. [PMID: 38675913 PMCID: PMC11055145 DOI: 10.3390/v16040570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 04/03/2024] [Accepted: 04/05/2024] [Indexed: 04/28/2024] Open
Abstract
Phage display is a versatile method often used in the discovery of peptides that targets disease-related biomarkers. A major advantage of this technology is the ease and cost efficiency of affinity selection, also known as biopanning, to identify novel peptides. While it is relatively straightforward to identify peptides with optimal binding affinity, the pharmacokinetics of the selected peptides often prove to be suboptimal. Therefore, careful consideration of the experimental conditions, including the choice of using in vitro, in situ, or in vivo affinity selections, is essential in generating peptides with high affinity and specificity that also demonstrate desirable pharmacokinetics. Specifically, in vivo biopanning, or the combination of in vitro, in situ, and in vivo affinity selections, has been proven to influence the biodistribution and clearance of peptides and peptide-conjugated nanoparticles. Additionally, the marked difference in properties between peptides and nanoparticles must be considered. While peptide biodistribution depends primarily on physiochemical properties and can be modified by amino acid modifications, the size and shape of nanoparticles also affect both absorption and distribution. Thus, optimization of the desired pharmacokinetic properties should be an important consideration in biopanning strategies to enable the selection of peptides and peptide-conjugated nanoparticles that effectively target biomarkers in vivo.

[PMID: 38396784 PMCID: PMC10889324 DOI: 10.3390/ijms25042107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 02/04/2024] [Accepted: 02/08/2024] [Indexed: 02/25/2024] Open
Abstract
The steadily increasing number of drug-resistant bacterial species has prompted the search for alternative treatments, resulting in a growing interest in bacteriophages. Although they are viruses infecting bacterial cells, bacteriophages are an extremely important part of the human microbiota. By interacting with eukaryotic cells, they are able to modulate the functioning of many systems, including the immune and nervous systems, affecting not only the homeostasis of the organism, but potentially also the regulation of pathological processes. Therefore, the aim of this review is to answer the questions of (i) how animal/human immune systems respond to bacteriophages under physiological conditions and under conditions of reduced immunity, especially during bacterial infection; (ii) whether bacteriophages can induce negative changes in brain functioning after crossing the blood-brain barrier, which could result in various disorders or in an increase in the risk of neurodegenerative diseases; and (iii) how bacteriophages can modify gut microbiota. The crucial dilemma is whether administration of bacteriophages is always beneficial or rather if it may involve any risks.

Abstract
Research on C-X-C motif chemokine ligand 10 (CXCL10) has been widely reported for humans and select animal species, yet immune reagents are limited for pig chemokines. Our goal is to provide veterinary immunologists and the biomedical community with new commercial immune reagents and standardized assays. Recombinant porcine CXCL10 (rPoCXCL10) protein was produced by yeast expression and used to generate a panel of α CXCL10 monoclonal antibodies (mAbs). All mAbs were assessed for cross-inhibition and reactivity to orthologous yeast expressed CXCL10 proteins. Characterization of a panel of nine α PoCXCL10 mAbs identified six distinct antigenic determinants. A sensitive quantitative sandwich ELISA was developed with anti-PoCXCL10-1.6 and -1.9 mAb; reactivity was verified with both rPoCXCL10 and native PoCXCL10, detected in supernatants of peripheral blood mononuclear cells stimulated with rPoIFNγ or PMA/Ionomycin. Immunostaining of in vitro rPoIFNγ stimulated pig spleen and blood cells verified CXCL10 + cells as CD3-CD4-CD172+, with occasional CD3-CD4 + CD172 + subsets. Comparison studies determined that α PoCXCL10-1.4 mAb was the ideal mAb clone for intracellular staining, whereas with α PoCXCL10-1.1 and -1.2 mAbs were best for immunohistochemistry analyses. These techniques and tools will be useful for evaluating swine immune development, responses to infectious diseases and vaccines, as well as for improving utility of pigs as an important biomedical model.
