## Abstract

Interleukin-6 (IL-6) is a critical cytokine involved
in immune
regulation, inflammation, and the pathogenesis of various diseases,
including autoimmune disorders, cancer, and the cytokine storm associated
with severe COVID-19. Identifying IL-6 inducing epitopes, the short
peptide fragments that trigger IL-6 production, is crucial for developing
epitope-based vaccines and immunotherapies. However, traditional methods
for epitope prediction often lack accuracy and efficiency. This study
presents RAG_MCNNIL6, a novel deep learning framework that integrates
Retrieval-augmented generation (RAG) with multiwindow convolutional
neural networks (MCNNs) for accurate and rapid prediction of IL-6
inducing epitopes. RAG_MCNNIL6 leverages ProtTrans, a state-of-the-art
pretrained protein language model, to generate rich embedding representations
of peptide sequences. By incorporating a RAG-based similarity retrieval
and embedding augmentation strategy, RAG_MCNNIL6 effectively captures
both local and global sequence patterns relevant for IL-6 induction,
significantly improving prediction performance compared to existing
methods. We demonstrate the superior performance of RAG_MCNNIL6 on
benchmark data sets, highlighting its potential for advancing research
and therapeutic development for IL-6-mediated diseases.
