Predicting the interaction between Major Histocompatibility Complex (MHC) class I-presented peptides and T-cell receptors (TCR) holds significant implications for vaccine development, cancer treatment, and autoimmune disease therapies. However, limited paired-chain TCR data, skewed towards well-studied epitopes, hampers the development of pan-specific machine-learning (ML) models. Leveraging a larger peptide-TCR dataset, we explore various alterations to the ML architectures and training strategies to address data imbalance...

Accurate computational identification of B-cell epitopes is crucial for the development of vaccines, therapies, and diagnostic tools. However, current structure-based prediction methods face limitations due to the dependency on experimentally solved structures. Here, we introduce DiscoTope-3.0, a markedly improved B-cell epitope prediction tool that innovatively employs inverse folding structure representations and a positive-unlabelled learning strategy, and is adapted for both solved and predicted structures...

BACKGROUND: Regulatory sandboxes offer an alternative solution to address regulatory challenges in adopting disruptive technologies.

OBJECTIVE: This study aims to explore stakeholders' perspectives on introducing a regulatory sandbox into the Indonesian health system using e-malaria as a use case...

MOTIVATION: Allergy is a pathological immune reaction towards innocuous protein antigens. Although only a narrow fraction of plant or animal proteins induce allergy, atopic disorders affect millions of children and adults and cost billions in healthcare systems worldwide. In silico predictors can aid in the development of more innocuous food sources. Previous allergenicity predictors used sequence similarity, common structural domains, and amino acid physicochemical features. However, these predictors strongly rely on sequence similarity to known allergens and fail to predict protein allergenicity accurately when similarity diminishes...

People with acute psychiatric conditions experience heightened stress, which is associated with worsened symptoms and increased violence on psychiatric wards. Traditional stress management techniques can be challenging for patients. Virtual reality (VR) relaxation appears promising to reduce stress; however, research on VR for psychiatric wards is limited. This mixed-methods study investigated feasibility and acceptability of integrating a VR relaxation clinic within acute psychiatric services. The study evaluated a VR relaxation session for inpatients and outpatients with acute psychiatric conditions (N = 42) and therapists' (N = 6) experience facilitating VR sessions for patients...

Digital health solutions could alleviate the needs of vulnerable populations in the recent period of the permacrisis, however, there are several barriers that limit their use for certain individuals. We use the four-pillar model of the novel concept of techquity to provide original evidence of the discrepancy in the willingness to try and the ability to harness healthtech in Hungary. We identified three underserved segments of society: older adults, people with long-term activity-limiting conditions, and people experiencing homelessness who could greatly benefit from digital technologies and yet use them less than the general population...

Digital health has become indispensable and inseparable from the current healthcare system. However, it is still often presented as a mysterious world that needs to be tamed in order to participate in innovations from their conception and to best accompany patients towards improving the quality and safety of care.

BACKGROUND: Healthtech has become a nascent sector of the internet economy since the emergence of the COVID-19 pandemic in 2020. Telemedicine features are facilitated, such as teleconsultation, e-diagnosis, e-prescribing, and e-pharmacy. However, the intention to use digital health services in Indonesia is still underdeveloped though the sales of other risk-free e-commerce products are high enough. OBJECTIVE: This study aims to assess the human perception of perceived value and social influences regarding the intention to use digital health services...

Human leukocyte antigen (HLA) class II antigen presentation is key for controlling and triggering T cell immune responses. HLA-DQ molecules, which are believed to play a major role in autoimmune diseases, are heterodimers that can be formed as both cis and trans variants depending on whether the α- and β-chains are encoded on the same (cis) or opposite (trans) chromosomes. So far, limited progress has been made for predicting HLA-DQ antigen presentation. In addition, the contribution of trans-only variants (i...

Luxembourg's supercomputer MeluXina is open to cooperation with companies that need to process huge quantities of data. Diem Bui, Solution Engineer at LuxProvide that manages MeluXina, explains how healthtech companies can benefit from supercomputing to develop and implement innovative health technology applications.

T cell receptors (TCR) define the specificity of T cells and are responsible for their interaction with peptide antigen targets presented in complex with major histocompatibility complex (MHC) molecules. Understanding the rules underlying this interaction hence forms the foundation for our understanding of basic adaptive immunology. Over the last decade, efforts have been dedicated to developing assays for high throughput identification of peptide-specific TCRs. Based on such data, several computational methods have been proposed for predicting the TCR-pMHC interaction...

B-cell epitope prediction tools are of great medical and commercial interest due to their practical applications in vaccine development and disease diagnostics. The introduction of protein language models (LM), trained on unprecedented large datasets of protein sequences and structures, tap into a powerful numeric representation that can be exploited to accurately predict local and global protein structural features from amino acid sequences only. In this paper, we present BepiPred-3.0, a sequence-based epitope prediction tool that, by exploiting LM embeddings, greatly improves the prediction accuracy for both linear and conformational epitope prediction on several independent test sets...
