High-Throughput Sequencing technologies are transforming many research fields, including the analysis of phage display libraries. The phage display technology coupled with deep sequencing was introduced more than a decade ago and holds the potential to circumvent the traditional laborious picking and testing of individual phage rescued clones. However, from a bioinformatics point of view, the analysis of this kind of data was always performed by adapting tools designed for other purposes, thus not considering the noise background typical of the 'interactome sequencing' approach and the heterogeneity of the data. InteractomeSeq is a web server allowing data analysis of protein domains ('domainome') or epitopes ('epitome') from either Eukaryotic or Prokaryotic genomic phage libraries generated and selected by following an Interactome sequencing approach. InteractomeSeq allows users to upload raw sequencing data and to obtain an accurate characterization of domainome/epitome profiles after setting the parameters required to tune the analysis. The release of this tool is relevant for the scientific and clinical community, because InteractomeSeq will fill an existing gap in the field of large-scale biomarkers profiling, reverse vaccinology, and structural/functional studies, thus contributing essential information for gene annotation or antigen identification. InteractomeSeq is freely available at https://InteractomeSeq.ba.itb.cnr.it/.

The cell surface display system employs carrier proteins to present target proteins on the outer membrane of cells. This system enables functional proteins to be exposed on the exterior of living cells without cell lysis, allowing direct interaction with the surrounding environment. A major limitation of conventional approaches is the difficulty in displaying large-sized enzymes or antibodies, despite their critical roles in applications requiring functional domains that must remain intact, such as catalytic or antigen-binding sites.

Most chemotherapeutics distribute non-specifically throughout the body, resulting in off-target toxicities. Nanoparticle (NP) formulations provide a strategy to improve drug delivery by extending circulation time, protecting therapeutic agents from degradation, and enabling controlled release. However, delivering NPs effectively to solid tumors remains challenging due to the barriers within the tumor microenvironment.

Thymic stromal lymphopoietin (TSLP) is an epithelial cell-derived cytokine that plays a crucial role in the pathophysiology of asthma, initiating multiple allergic cascade responses. Tezepelumab is the only monoclonal antibody currently approved for marketing, which acts by blocking TSLP binding to TSLPR. However, it is reported that a TSLP trap which simultaneously block TSLP binding with TSLPR and IL-7Rα has better efficiency in the repression of TSLP signal pathway.

Highly pathogenic avian influenza (HPAI) H5N1 virus poses a continuing global public health threat due to its outbreaks in poultry farms and zoonotic transmission from birds to humans. In the quest of effective therapeutics against H5N1 infection, antibodies with broad neutralizing activity have attracted significant attention. In this study, we employed a phage display technique to select and identify VHH antibodies with specific neutralizing activity against H5N1 hemagglutinin (HA) from an immune llama-derived antibody library.

Vascular endothelial growth factor (VEGF) is a key player in the development and progression of several diseases, most notably cancer and retinal disorders. Over the last twenty years, VEGF has emerged as a significant therapeutic target for these conditions. This study reports the isolation and characterization of a fully synthetic, humanized, affinity-matured single-domain antibody fragment (VHH) designed to target VEGF.
