背景介紹：Neurofilaments can be defined as the intermediate or 10nm filaments found in specifically in neuronal cells. When visualised using an electron microscope, neurofilaments appear as 10nm diameter fibres of indeterminate length that generally have fine wispy protrusions from their sides. They are particularly abundant in axons of large projection neurons. They probably function to provide structural support for neurons and their synapses and to support the large axon diameters required for rapid conduction of impulses down axons. Neurofilaments are composed of a mixture of subunits, which usually includes the three neurofilament triplet proteins neurofilament light (NFL), neurofilament medium (NFM) and neurofilament heavy (NFH). Neurofilaments may also include smaller amounts of peripherin, alpha internexin, nestin and in some cases vimentin. Antibodies to the various neurofilament subunits are very useful cell type markers since the proteins are among the most abundant of the nervous system, are expressed only in neurons, and are biochemically very stable. Some studies have shown that levels of neurofilament heavy and neurofilament light are elevated in patients with Alzheimer's disease, frontotemporal lobe dementia, and vascular dementia.

免疫應答

    抗原刺激機體產(chǎn)生相應的抗體，抗體的產(chǎn)生過程即為體液免疫應答過程。

    體液免疫應答的主要*位是淋巴結、脾臟和粘膜下淋巴組織等外周免疫器官，外來抗原進入機體后即被補體致敏或者被DC吞噬，然后隨淋巴液進入引流淋巴結。淋巴濾泡中的FDC通過其表面的補體受體捕獲被致敏的外來抗原，激活B細胞。位于脾髓質交界區(qū)的DC則為T細胞呈遞外來抗原肽，啟動獲得性免疫應答，B細胞在外周成熟、發(fā)育過程的zui后階段是成為專門的合成和分泌抗體分子的漿細胞。漿細胞高爾基體發(fā)達、代謝活躍，但沒有繼續(xù)分裂、增殖的能力，也不參與抗原遞呈。他們寄居在脾臟或者骨髓中，集中所有的能量生產(chǎn)并分泌抗體分子?？贵w分子的重鏈和輕鏈在內質網(wǎng)上合成、組裝后經(jīng)高爾基體運輸至細胞表面并分泌于胞外。一個漿細胞每秒鐘能分泌5000個抗體分子，在外周的漿細胞壽命僅為幾天，但是骨髓中的漿細胞壽命可能較長。

免疫應答過程：

1.抗原進入機體；

2.抗原刺激 B淋巴細胞，使之分化增殖成為抗體分泌漿細胞和記憶細胞（初次免疫應答）；

3.抗體主要由漿細胞分泌 ；

4.記憶細胞再次受到特異性抗原刺激后會被激活而成為分泌抗體的漿細胞（再次免疫應答）；

5.記憶B細胞是長命細胞，可以存活數(shù)月甚至機體終生
