Oral immunology encompasses the study of the immune system within the oral cavity, focusing on its role in protecting against pathogens, maintaining oral health, and contributing to the pathogenesis of oral diseases. This multifaceted field delves into the intricate interactions between immune cells, oral tissues, and microbial communities, shedding light on the mechanisms underlying immune responses in the mouth. At the forefront of oral immunology lies the mucosal immune system, which serves as the first line of defence against invading pathogens while maintaining tolerance to harmless antigens, such as food particles and commensal bacteria. The oral mucosa harbour’s a diverse array of immune cells, including macrophages, dendritic cells, T cells, B cells, and specialized subsets such as intraepithelial lymphocytes, each playing unique roles in immune surveillance and regulation. One of the key features of the oral mucosal immune system is its ability to discriminate between harmless antigens and potential threats, orchestrating appropriate immune responses to maintain homeostasis. This delicate balance is maintained through a complex network of immune cells and soluble factors, including cytokines, chemokine’s, and antimicrobial peptides, which regulate immune cell recruitment, activation, and effector functions. In addition to its role in host defence, the oral immune system is intimately involved in the pathogenesis of various oral diseases, including periodontal disease, oral infections, autoimmune conditions, and oral cancers. Dysregulation of immune responses within the oral cavity can lead to chronic inflammation, tissue destruction, and susceptibility to infections, contributing to the development and progression of oral diseases. Periodontal disease, for example, is characterized by an inflammatory response to microbial plaque accumulation, leading to destruction of the supporting tissues surrounding the teeth. Immune cells, particularly neutrophils, macrophages, and T cells, play pivotal roles in orchestrating the inflammatory cascade within the periodontal tissues, exacerbating tissue damage and bone loss. Similarly, oral infections such as candidiasis, caused by the opportunistic fungal pathogen Candida albicans, highlight the interplay between the immune system and microbial pathogens in the oral cavity. In healthy individuals, innate and adaptive immune mechanisms effectively control Candida colonization; however, immune suppression or dysregulation can predispose individuals to fungal overgrowth and infection. Autoimmune conditions affecting the oral cavity, such as oral lichen planus and pemphigus vulgaris, involve aberrant immune responses targeting self-antigens within oral tissues, leading to tissue damage and ulceration. Understanding the underlying immunopathogenesis of these conditions is essential for developing targeted therapeutic strategies to modulate immune responses and alleviate symptoms. Moreover, the oral mucosa serves as a site for immune surveillance against oral cancers, which arise from deregulated cell growth within the oral epithelium. Immune cells infiltrating the tumour microenvironment, including tumour-associated macrophages, T cells, and regulatory T cells, play critical roles in modulating Anti-tumour immune responses and influencing disease progression. Advancements in oral immunology have paved the way for innovative diagnostic and therapeutic approaches aimed at harnessing the immune system to combat oral diseases. Immunomodulatory therapies, such as immune checkpoint inhibitors and therapeutic vaccines, hold promise for enhancing Anti-tumour immune responses and improving outcomes for patients with oral cancers.
