[Abstract] In this protocol we describe how to visualize neutrophil extracellular traps (NETs) and fungal cell wall changes in the context of the coculture of mouse neutrophils with fungal hyphae of Candida albicans. These protocols are easily adjusted to test a wide array of hypotheses related to the impact of immune cells on fungi and the cell wall, making them promising tools for exploring host-pathogen interactions during fungal infection.
[摘要] 在本协议中，我们描述了如何在小鼠嗜中性粒细胞与真菌白色念珠菌的真菌菌丝共培养的背景下观察嗜中性粒细胞胞外捕获物（NETs）和真菌细胞壁变化。 这些方案很容易调整，以测试与免疫细胞对真菌和细胞壁的影响有关的各种假设，使其成为探索真菌感染期间宿主病原体相互作用的有前景的工具。
C。白色念珠菌是一种多态性机会性酵母，嗜中性粒细胞是免疫细胞，对于这种和其他真菌病原体的防御至关重要（Brown等，2012; Lionakis和Netea，2013）。 NETs是可以针对病原体部署的潜在防御机制，并且已经表明它们优先针对诸如C的微生物细胞部署。白念珠菌菌丝太大而不能吞噬（Urban et al。，2006; Bruns等人，2010; Branzk等人，，2014; Rohm等人，2014）。 NET已经显示含有许多组分，包括髓过氧化物酶，胞外DNA和瓜氨酸化的组蛋白（Amulic等人，2012; ...

[Abstract] Natural Killer (NK) cells are cytotoxic lymphocytes that constitute a major component of the innate immune system. Immunosurveillance of the host by NK cells for malignant and virally-infected cells results in direct cytotoxicity and the production of cytokines to enhance the immune response. This protocol will describe the “gold standard” chromium release assay for measuring the target cell killing capacity of NK cells. Key features of this cytotoxicity assay are that it is performed with sorted NK cells as the effectors and any Major Histocompatibility Class I (MHC-I)-low or deficient tumor cell line can be used as the target cells.
[摘要] 天然杀伤（NK）细胞是细胞毒性淋巴细胞，其构成先天性免疫系统的主要组分。 通过NK细胞对恶性和病毒感染的细胞的宿主的免疫监视导致直接的细胞毒性和细胞因子的产生，以增强免疫应答。 该方案将描述用于测量NK细胞的靶细胞杀伤能力的"金标准"铬释放测定。 该细胞毒性测定的主要特征是其使用分选的NK细胞作为效应物进行，任何主要组织相容性I类（MHC-1） - 低或缺陷的肿瘤细胞系可以用作靶细胞。

[Abstract] Natural Killer (NK) cells are cytotoxic lymphocytes that constitute a major component of the innate immune system. Immunosurveillance of the host by NK cells for malignant and virally-infected cells results in direct cytotoxicity and the production of cytokines to enhance the immune response. This protocol will describe the adoptive transfer of purified NK cells into NK cell-deficient tumor bearing mice in order to establish the intrinsic functionality of NK cells.
