活化的免疫细胞,如巨噬细胞“M1”、树突状细胞(DCs)、固有淋巴样细胞(ILC2)、NK 细胞、Th1、滤泡性 T 辅助细胞(TFH)、TCD8+、B 淋巴细胞和嗜酸性粒细胞,对肿瘤发生具有抑制作用,而耐受性细胞,如巨噬细胞“M2”、耐受性 DCs、ILC3、T 和 B 调节性淋巴细胞,似乎有利于癌变。肥大细胞和警报素可具有双重作用。RIgE 抗体和 CCCL5 趋化因子具有抗癌作用,而 IgG4、游离轻链、Il-10、TGF-β、lipocalin-2、CCL1 趋化因子则促进癌症进展。由 microRNA 调控的表观遗传学改变在癌症进展中的作用也至关重要。
免疫细胞和免疫蛋白在宿主对病原体、过敏原和癌症的反应中发挥关键作用。理解过敏反应与癌症之间的相互作用、免疫监视、免疫调节、免疫球蛋白 E(IgE)介导功能的作用,有助于开发新的治疗策略。过敏和肿瘤学呈现出两种相反的情形:过敏中需要免疫耐受,而在癌症中免疫耐受则是有害的。
本综述提供了免疫细胞和免疫蛋白在过敏和癌症领域中作用的更新。
作者研究了相关免疫标志物的作用及其与癌症进展或癌症抑制的相关性。

Immune cells and immune proteins play a pivotal role in host responses to pathogens, allergens and cancer. Understanding the crosstalk between allergic response and cancer, immune surveillance, immunomodulation, role of immunoglobulin E (IgE)-mediated functions and help to develop novel therapeutic strategies. Allergy and oncology show two opposite scenarios: whereas immune tolerance is desired in allergy, it is detrimental in cancer. AIM: The current review provides an update on the role of immune cells and immune proteins in allergy and cancer fields.
Authors investigated the role of relevant immunological markers and the correlation with cancer progression or cancer suppression.
Activated immune cells such as macrophages 'M1', dendritic cells (DCs), innate lymphoid cells (ILC2), NK cells, Th1, follicular T helper cells (TFH), TCD8+, B lymphocytes and eosinophils have inhibitory effects on tumourigenesis, while tolerogenic cells such as macrophages 'M2,' tolerogenic DCs, ILC3, T and B regulatory lymphocytes appear to favour carcinogenesis. Mastocytes and alarmins can have both effects. RIgE antibodies and CCCL5 chemokine have an anticancer role, whereas IgG4, free light chains, Il-10, TGF-β, lipocalin-2, CCL1 chemokine promote cancer progression. Fundamental is also the contribution of epigenetic changes regulated by the microRNA in cancer progression.
This knowledge represents the key to developing new anticancer therapies.
