While non-ionizing radiation is relatively harmless, ionizing radiation possesses sufficient energy to ionize atoms and disrupt DNA, leading to cell damage, mutation, cancer, and cell death. The extensive use of radionuclides and ionizing radiation in nuclear technology and medical applications has sparked global concern for their capacity to cause acute and chronic illnesses. Ionizing radiation induces DNA damage either directly through strand breaks and base change or indirectly by generating reactive oxygen species (ROS) and reactive nitrogen species (RNS) via radiolysis of water. This damage triggers a complex cellular response involving recognition of DNA damage, cell cycle arrest, DNA repair mechanisms, release of pro-inflammatory cytokines, and cell death. This review focuses on the mechanisms of radiation-induced cellular damage, recognition of DNA damage and subsequent activation of repair processes, and the critical role of the innate immune response in resolution of the injury. Emphasis is placed on pattern recognition receptors (PRRs) and related receptors that detect damage-associated molecular patterns (DAMPs) and initiate downstream signaling pathways. Radiation-induced cell death pathways are discussed in detail. Understanding these processes is crucial for developing strategies to mitigate the harmful effects of radiation and improve therapeutic outcomes.</p>","PeriodicalId":178,"journal":{"name":"Immunological Reviews","volume":" ","pages":"e13409"},"PeriodicalIF":7.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11742653/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142454231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CTLA-4, PD-1, and LAG3 are three co-inhibitory receptors, which can be expressed by subsets of T cells and which play a role in the regulation of adaptive immune responses. Blocking these immune checkpoints receptors (or their ligands) with antagonistic antibodies can lead to tumor regressions and lasting remissions in some patients with cancer. Two anti-CTLA4, six anti-PD1, three anti-PD-L1, and one anti-LAG3 antibodies are currently approved by the FDA and EMA. Their mechanism of action, safety, and efficacy are linked to their affinity with Fc gamma receptors (FcγR) (so called “effector functions”). The anti-CTLA-4 antibodies ipilimumab (IgG1) and tremilimumab (IgG2a), and the anti-PD-L1 avelumab (IgG1) have isotypes with high affinity for activating FcγR and thereby can induce ADCC/ADCP. The effector function is required for the in vivo efficacy of anti-CTLA4 antibodies. For anti-PD(L)1 antibodies, where a pure antagonistic function (“checkpoint blockade”) is sufficient, some mAbs are IgG1 but have been mutated in their Fc sequence (e.g., durvalumab and atezolizumab) or are IgG4 (e.g., nivolumab and pembrolizumab) to have low affinity for FcγR.

Everyone knows that antibodies protect against infectious diseases, especially since the COVID-19 pandemic swept across the world. Everyone, or almost, even knows what antibodies look like. Their anthropomorphic Y shape has become an iconic symbol that most societies of immunology have included in their logo. What antibodies actually are, however, is not so clear in everyone's mind, as judged by media which often confuse serum with vaccine. What antibodies do and how they work is another question. Their well-known ability to recognize specific antigens with each of their two “arms” is often thought to be enough to protect; even by scientists, sometimes by immunologists. Whatever how, antibodies protect, and when they have pathogenic effects, these are viewed as the unfortunate consequences of targeting errors such as in allergic and autoimmune diseases, or collateral damages such as in inflammatory diseases.</p><p>Antibodies are also well known as tools. Due to their exquisite specificity, antibodies have proven unrivaled diagnostic tools and they are used in a variety of techniques adopted by all medical disciplines and beyond. Due to their powerful biological properties, antibodies have been increasingly used as therapeutic tools with amazing efficiencies. This is not new: antibodies saved thousands of children from diphtheria and many more wounded soldiers from tetanus at the beginning of the 20th century, when they were nothing but elusive substances in immune serum. They are well-known molecules now and, as serum therapy for deadly infectious diseases yesterday, humanized monoclonal antibodies have provided long-sought cures for cancers with a poor prognosis today. Not without side effects, though. But antibodies can be engineered genetically to enhance their expected effects and to decrease their unwanted effects.</p><p>Why, therefore, put together another series of review articles on such well-known molecules? As stated in its title, this volume of <i>Immunological Reviews</i> is focused on the <i>effector functions</i> of antibodies. Antibodies are bi-functional molecules: They can not only recognize antigens; they can also act on them. How they do so is poorly known by immunologists, except those who work specifically on the subject. Yet, antibodies are the main effectors of adaptive immunity, at least quantitatively: 10 mg/mL IgG and 2–3 mg/mL IgA circulate in the blood stream—and much more are present in tissues since 80% immunoglobulin-secreting plasma cells of the whole body produce mucosal IgA. How do these antibodies deal with pathogens and commensals? How can they both prevent infections and tolerate microbiotas without inducing devastating inflammatory reactions? How antibodies induced by vaccines exert their protective effects?</p><p>This volume deals with the effector functions of antibodies not only in health, but also in disease.

IgA is essential for immune homeostasis and education. Mucosal IgA plays a crucial role in maintaining the integrity of the mucosal barrier by immune exclusion of pathobionts while facilitating colonization with certain commensals; a large part of the gut microbiota is coated with IgA. In the circulation, monomeric IgA that has not been engaged by antigen plays a discrete role in dampening inflammatory responses. Protective and harmful roles of IgA have been studied over several decades, but a new understanding of the complex role of this immunoglobulin in health and disease has been provided by recent studies.

While the system is designed such that these receptors should specifically recognize pathogen-derived nucleic acids, it is now clear that self-derived RNA and DNA can also stimulate these receptors to cause aberrant inflammation and autoimmune disease. Intriguingly, similar pathways are now emerging in the central nervous system in neurons and glial cells. As in the periphery, these signaling pathways are active in neurons and glia to present the spread of pathogens in the CNS. They further appear to be active even under steady conditions to regulate neuronal development and function, and they can become activated aberrantly during disease to propagate neuroinflammation and neurodegeneration.

For this provocative finding, Charles Richet was awarded the 1913 Nobel Prize in Physiology or Medicine. Because, as its name said, anaphylaxis was understood as “the contrary of protection,” unique mechanisms were found to explain it. Because, as its name did not initially say but finally said, allergy was understood as a reaction “other” than immunity, its symptoms were explained by mechanisms similar to those that explained anaphylaxis. We examined here the intricate relationships between anaphylaxis, allergy and immunity. Progressively anaphylaxis became one among other pathological effects of an immune response, and allergy an inflammatory disease among others.
