Immune biomarkers are fundamental to comprehending disease pathogenesis, predicting patient outcomes, and directing therapeutic interventions, particularly in the realm of immunopathology. Recent scientific endeavors are concentrating on the identification of novel molecular signatures that accurately reflect specific immune responses, thereby facilitating more precise patient stratification and the implementation of personalized medicine strategies. [1] The landscape of immune biomarkers is undergoing rapid evolution, marked by a substantial impetus towards high-throughput technologies such as single-cell RNA sequencing and multiplex assays. These advanced methodologies permit the comprehensive profiling of immune cells and their functional states, offering an unprecedented level of resolution for dissecting complex immune responses across a variety of pathological conditions. [2] Biomarkers for immune-related adverse events (irAEs) are of critical importance in the management of patients undergoing immunotherapy. The ability to identify predictive biomarkers for irAEs can significantly aid in patient stratification and the tailoring of prophylactic or treatment strategies, ultimately enhancing the safety and tolerability of these life-saving therapies. [3] The influence of the microbiome on the modulation of immune responses is increasingly being recognized, prompting the exploration of microbial metabolites and species as potential immune biomarkers. These biomarkers have the capacity to offer valuable insights into immune homeostasis and an individual's susceptibility to immune-mediated diseases. [4] Cytokines and chemokines continue to serve as foundational immune biomarkers, providing a functional readout of immune cell activation and intercellular communication. Advancements in multiplex cytokine assays now enable the simultaneous measurement of numerous analytes, thus revealing intricate cytokine networks in both health and disease states. [5] Extracellular vesicles (EVs), including exosomes, are emerging as significant reservoirs of immune biomarkers. The molecular cargo contained within EVs, such as proteins, nucleic acids, and lipids, can accurately reflect the physiological or pathological state of their parent cells, furnishing valuable diagnostic and prognostic information. [6] Cell-free DNA (cfDNA), particularly its integrity and fragmentation patterns, is progressively gaining recognition as a non-invasive immune biomarker. Elevated levels and altered patterns of cfDNA can signify tissue damage and inflammatory processes, holding potential applications in the diagnosis and monitoring of diverse diseases. [7] The analysis of circulating tumor DNA (ctDNA) is fundamentally transforming cancer diagnostics and patient monitoring. Beyond its association with oncogenic mutations, ctDNA can also harbor immune-related signatures, including neoantigens and T-cell receptor sequences, thereby providing crucial insights into the tumor immune microenvironment. [8] The burgeoning field of immunometabolism is identifying specific metabolic pathways and their associated metabolites as novel immune biomarkers. A comprehensive understanding of the metabolic state of immune cells can serve as a predictor of their functional capabilities and their impact on disease progression, potentially uncovering new therapeutic targets. [9] Artificial intelligence (AI) and machine learning (ML) are assuming an increasingly critical role in both the discovery and validation of immune biomarkers. These advanced computational approaches possess the capability to analyze complex, high-dimensional datasets, enabling the identification of subtle patterns indicative of disease states or therapeutic responses that might otherwise escape detection by conventional methods.

Immune biomarkers play a pivotal role in deciphering the complexities of disease pathogenesis, predicting patient prognoses, and guiding the selection of effective therapeutic interventions, especially within the field of immunopathology. Current research is heavily focused on identifying novel molecular signatures that can accurately represent specific immune responses, thereby enabling more precise patient stratification and the development of personalized medicine approaches. [1] The domain of immune biomarkers is experiencing a period of rapid advancement, with a significant shift towards the adoption of high-throughput technologies. Methodologies like single-cell RNA sequencing and multiplex assays are at the forefront, allowing for an exhaustive profiling of immune cells and their functional states. This offers an unparalleled resolution for dissecting intricate immune responses observed in various pathological conditions. [2] For patients undergoing immunotherapy, the identification of biomarkers associated with immune-related adverse events (irAEs) is paramount for effective management. The capability to predict irAEs through biomarkers allows for better patient stratification and the formulation of tailored prophylactic or treatment plans, ultimately improving the safety and tolerance of these critical therapies. [3] The intricate relationship between the microbiome and the immune system is becoming increasingly apparent, leading to the investigation of microbial metabolites and species as potential immune biomarkers. Such biomarkers could provide essential insights into the maintenance of immune homeostasis and an individual's susceptibility to diseases mediated by the immune system. [4] Cytokines and chemokines continue to be indispensable immune biomarkers, offering a direct functional assessment of immune cell activation and communication. The development of multiplex cytokine assays has revolutionized the field by enabling the simultaneous measurement of a wide array of analytes, thus unveiling complex cytokine interactions in both health and disease. [5] Extracellular vesicles (EVs), which encompass exosomes, are emerging as crucial sources of immune biomarkers. The diverse molecular content of EVs, including proteins, nucleic acids, and lipids, can effectively mirror the physiological or pathological status of their originating cells, thereby offering valuable diagnostic and prognostic information. [6] Cell-free DNA (cfDNA), specifically its fragmentation patterns and integrity, is gaining significant traction as a non-invasive immune biomarker. Elevated concentrations and altered fragmentation of cfDNA can indicate underlying tissue damage and inflammatory processes, presenting potential applications in the diagnosis and monitoring of a broad spectrum of diseases. [7] The analysis of circulating tumor DNA (ctDNA) is ushering in a new era of cancer diagnostics and treatment monitoring. Beyond its role in detecting oncogenic mutations, ctDNA can also reveal immune-related signatures, such as neoantigens and T-cell receptor sequences, thereby shedding light on the tumor's immune microenvironment. [8] The rapidly developing field of immunometabolism is identifying metabolic pathways and their associated metabolites as promising new immune biomarkers. Understanding the metabolic state of immune cells can offer predictive insights into their functional capacity and their influence on disease progression, potentially opening avenues for novel therapeutic strategies. [9] Artificial intelligence (AI) and machine learning (ML) are becoming indispensable tools in the discovery and validation of immune biomarkers. These computational techniques are capable of analyzing vast and complex datasets, identifying subtle patterns that indicate disease states or predict treatment responses, which might be overlooked by traditional analytical methods.

Immune biomarkers are critical for understanding disease, predicting outcomes, and personalizing treatments. Advancements in high-throughput technologies like single-cell RNA sequencing and multiplex assays allow for detailed immune cell profiling. Biomarkers are essential for managing immunotherapy side effects and understanding the microbiome's role in immunity. Cytokines, chemokines, extracellular vesicles, and cell-free DNA are key areas of research. Circulating tumor DNA offers insights into the tumor microenvironment, while immunometabolism and AI are emerging frontiers in biomarker discovery. These innovations promise more precise diagnostics and tailored therapeutic strategies across various diseases.
