These membrane nanotubes might, for example, constitute a previously unknown mechanism for immune cell communication by allowing directed secretion of cytokines between cells far apart. Simon C. Watkins and Russell D. Salter of the University of Pittsburgh School of Medicine have found that a population of immune cells could use such nanotubular highways to transmit calcium signals across vast (for cells) distances of hundreds of microns within seconds.

In the future, more studies of interactions among larger groups of immune cells could reveal additional aspects of immune cell communication networks. Imaging immune cell interactions as they traffic inside living organisms, rather than on a slide, is another important frontier for this line of research.

In a recent memoir, Nobel laureate John Sulston described using cutting edge microscopy in the 1970s to understand worm development: "Now to my amazement, I could watch the cells divide. Those Nomarski images of the worm are the most beautiful things imaginable … In one weekend I unraveled most of the postembryonic development of the ventral cord, just by watching."

High-resolution microscopy of immune cell interactions is still a very young field, and more Surprises are surely in store. Virtually all the surface proteins involved in immune cells' recognition of disease have been identified and named. But the ability of scientists to now observe as these molecules play out their roles in space and time has revealed the immune synapse mechanism and reconfirmed the value of "just watching" as a scientific method.

    這些膜nanotubes 也許, 例如, 構成一個早先未知的機制為免疫細胞通信由分開允許cytokines 的被指揮的分泌物在細胞之間。西蒙・C. Watkins 和Russell D. Salter 匹茲堡醫學院大學發現免疫細胞的人口能使用這樣nanotubular 高速公路傳送鈣信號橫跨浩大的(為細胞) 距離上百微米在幾秒鐘內。

    在將來, 更多互作用的研究在更大的小組免疫細胞之中能顯露免疫細胞通訊網路的另外的方面。想像免疫細胞互作用因為他們交易在生物裡面, 而不是在幻燈片, 是其它重要邊境為研究這條線。在一個最近專刊, 諾貝爾得獎者約翰・Sulston 被描述使用先鋒顯微學在70 年代瞭解蠕蟲發展: "現在對我的觸目驚心, 我能觀看細胞劃分。那些蠕蟲的Nomarski 圖像是最美好的事能想像... 在一個週末我解開了大多數腹繩子的postembryonic 發展, 觀看。"

    免疫細胞互作用高分辨率顯微學是仍然一個非常年輕領域, 並且更多驚奇肯定是商店。實際上所有表面蛋白質被介入在疾病的免疫細胞的認識被辨認了和被命名了。但科學家的能力現在觀察當這些分子扮演他們的在空間和時間的角色顯露了免疫突觸機制和再確認"觀看的" 價值作為一個科學方法。
