In recent years, multiple studies have been published, in which TLRs were the main object of research. Particular studies were focused on the following aspects regarding Toll-like receptors: their structure, ligand recognition, signal transduction, and modulator design. Some of these works were done with the use of in silico methods. Due to the increase in the use of computational techniques, it was our goal to summarise how various in silico solutions have contributed to a better understanding of TLRs. More than five years have passed since the last published reviews on this topic , and we decided to gather the latest relevant results in this paper. We summarised the research conducted so far, while also emphasising in which areas we still lack knowledge or solutions. In this work, we focused exclusively on research on human Toll-like receptors (hTLRs).
