免疫細胞作戰場景特寫

2018-02-09 癌圖騰


橙色的是細胞毒性T細胞(cytotoxic T cells),藍色的是癌細胞


其中最主要有兩類,一類是B細胞,這一類細胞實際上是二炮,發射導彈,對病菌感染進行抑制,對病菌進行清除,這是體液免疫。另外是代表性的T淋巴細胞,T細胞的發揮我們常說是細胞免疫。(以上動圖就是T細胞殺死癌細胞的過程)



A macrophage (x18000), a human defense cell, seeking to engulf droplets of oil.

巨噬細胞 嘗試吞噬油滴


A major component of the immune system, a helper t-cell is under attack by Hiv/ AIDS (blue)

輔助t細胞(白細胞)正被Hiv病毒(愛滋/藍色)攻擊


latecomers in immunesystem evolution, B-cells, like this specimen covered with bacteria, produce armies of anti-bodies whose sole purpose is to attack a single kind of pathogen.

B細胞(淋巴細胞)產生特定抗體針對單一病原體,圖上B細胞被細菌覆著


Malaria protozoa have multiplied in two cells in a culture dish of red blood cells. One has burst open releasing the parasites to infect other cells

瘧原蟲分裂成2個個體,周圍是紅細胞,其中一個瘧原蟲已經破裂釋放繁殖子影響其它細胞


First line of defense agains armies of dangerous microorganisms, skin tissue is able to mend itself rapidly after injury.

對抗微生物的第一防線,皮膚組織受傷之后可以迅速修復。


First step in phagocytosis, or “cell eating” a macrophage extends several pseudopods from it’s singlecelled form to embrace a number of E-coli bacteria

吞噬的第一步,巨噬細胞伸展偽足包圍大腸桿菌


Bacteria trapped within an extension of a macrophage membrane

細菌被巨噬細胞延伸的細胞膜捕獲


Powerful chemicals inside the macrophage will breakdown and destroy the components of invading cells.

巨噬細胞分泌酶和過氧化物分解吞噬入侵細胞


Like a vision from science fiction, a macrophage reaches out to ensnare bacteria with a cellular extension called a pseudopod.

巨噬細胞伸展偽足捕捉細菌


One of mankind’s greatest inorganic threats, asbestos fibres are engulfed by a macrophage which will probably die from it’s indigestible meal.

巨噬細胞吞噬石棉纖維導致自身死亡


mutiny in the body is a constant occurrence, many believe, as healthy cells somehow escape the mechanisms that regulate cell growth and turn cancerous. Fortunately, antigens on their surfaces sometimes alter slightly, changing from self to non-self. Thus the cells become targets for Killer T-cells, like these surrounding this large cancer cell.

一些正常細胞脫離正常生長機制發生癌變,這些癌變細胞便成了細胞毒性t細胞(淋巴細胞)的獵物


Frozen in action, killer T cells appear remarkably alive as they attack a cancer cell. Several of the normally round T-cells acquire the elongated shape of active fighters as they subject their target to chemical attack, breaking down the cell membrane.

幾個圓形的細胞毒性t細胞伸長形體,利用穿孔素等化學物質破壞細胞膜,并釋放酶殺死病變細胞


After a cancer cell loses it’s cytoplasm, only a fibrous skelleton is left, here surrounding a T-cell.

癌細胞喪失了細胞質,只剩余纖維骨架,圖中有一個細胞毒性t細胞


Overzealous immune responses, allergic reactions plague humans who produce certain unnecessary antibodies.

過度免疫反應,過敏反應激發人體產生不必要的抗體 造成麻煩


A renegade immune system has ravaged a (surgically removed) femur of a 50 year old women suffering from Rheumatoid Arthritis. Most common of al the autoimmune disorders.

自體免疫障礙導致免疫系統攻擊關節的慢性疾?。愶L濕性關節炎),是一種最常見的自體免疫性疾病,圖為被免疫系統攻擊壞死的股骨頭


The common cold virus, constantly mutates to avoid detection. Just how totally viruses can overcome a healthy host is seen when an infected human cell ruptures, releasing a stream of new viruses (blue) into the system.

感冒病毒不斷變異來規避免疫系統,圖為人體細胞破裂釋放出新的病毒(藍色)。
