Research on toll-like receptors, specifically TLR2 and TLR4, is exploring their role in various physiological and pathological processes. These receptors appear to be involved in inflammation in different systems, including the reproductive system, as well as in other conditions such as periodontal inflammation, tumor development, and neuroinflammation. The study of toll-like receptors is also investigating their potential therapeutic applications, including mitigation of acute radiation syndrome and modulation of neuroinflammation in diseases like Alzheimer's.
