Introduction

The mucosal immune system comprises a sophisticated network of tissues and cells crucial for safeguarding the body against pathogens at mucosal surfaces. At the heart of this defense mechanism are mucosal cytokines, signaling molecules that coordinate immune responses [1,2]. This review explores the intricate realm of mucosal cytokines, shedding light on their diverse functions and pivotal roles in maintaining mucosal homeostasis.

Structural diversity and function

Mucosal cytokines display remarkable structural diversity, encompassing interleukins (IL), tumor necrosis factors (TNF), and interferons (IFN). Each cytokine family has distinct functions, contributing to the regulation of inflammation, immune cell activation, and tissue integrity maintenance [3]. Understanding the nuanced roles of specific cytokines is essential for unraveling the complexity of mucosal immunity.

Local and systemic impact: A key feature of mucosal cytokines is their ability to exert both local and systemic effects. These molecules play a crucial role in shaping the immune response at mucosal surfaces, influencing the behavior of immune cells such as T cells, B cells, and dendritic cells. Additionally, mucosal cytokines can impact distant organs and tissues, underscoring their systemic reach and significance in overall immune regulation [4,5].

Interplay with the microbiota: The microbiota, a vast community of commensal microorganisms, intricately interacts with mucosal cytokines. This dynamic interplay is vital for maintaining immune tolerance and preventing inappropriate inflammatory responses. The review explores how mucosal cytokines contribute to the delicate balance between host defense and tolerance in the presence of a diverse microbial community [6].

Implications for disease: A comprehensive understanding of mucosal cytokines is imperative for unraveling the pathogenesis of various diseases. Dysregulation of these signaling molecules has been implicated in conditions such as inflammatory bowel disease (IBD), allergies, and autoimmune disorders [7,8]. Investigating the specific cytokine profiles associated with different diseases opens avenues for targeted therapeutic interventions.

Emerging therapeutic opportunities: The review also highlights potential therapeutic applications of targeting mucosal cytokines. Advances in biologics and immunomodulatory therapies offer new opportunities for precision medicine in diseases characterized by mucosal inflammation [9]. Examining the current landscape of clinical trials and experimental interventions provides insights into the exciting prospects of manipulating mucosal cytokines for therapeutic purposes.
