There are three types of autophagy: macroautophagy, microautophagy, and chaperone-mediated autophagy (Fig. 1).
Psoriasis ...[71], and pathologically characterized by inflammation and epidermal
proliferation.
Several pathogens, such as bacteria, viruses and even fungi, have been linked
to psoriasis [72].
自噬共有三種類型:宏觀自噬,微自噬和伴侶介導的自噬(圖1)。
乾癬... [71],其病理特徵是炎症和表皮增生。
幾種病原體,如細菌,病毒,甚至真菌,都與乾癬有關[72]。
A study showed that the ratios of Th17 to Treg cells were significantly higher in the patients with psoriasis than those in the normal controls, which demonstrated that the balance between Th17 and Treg plays an important role in the pathogenesis of psoriasis.
As stated above, autophagy was enhanced when Th17 decreased and Treg cells increased.
The ratio of Th17 to Treg cells was elevated in patients with psoriasis; thus,
decreased autophagy could affect psoriasis through Th17 and Treg cells.
一項研究表明,乾癬患者中Th17與Treg細胞的比率明顯高於正常對照組,這表明Th17和Treg之間的平衡在乾癬的發病中起著重要作用。
如上所述,當Th17減少而Treg細胞增加時,自噬被增強。乾癬患者中Th17與Treg細胞的比例升高;因此,自噬減少可能通過Th17和Treg細胞影響乾癬。
Psoriasis is characterized by heavily scaled red plaques. The excessive epithelial
keratinocyte (KC) proliferation and abnormal apoptosis are important features of
psoriasis [88], and inhibition of the excessive proliferation of KCs is an effective treatment method [89].
Studies have recently shown that autophagy deficiency leads to inflammatory cytokine production and cell proliferation in KCs [90].
乾癬的特點是紅色斑塊嚴重。過度的上皮角質形成細胞(KC)增殖和異常凋亡是乾癬的重要特徵[88],抑制KCs過度增殖是一種有效的治療方法[89]。
最近的研究表明,自噬不足會導致炎症細胞因子的產生和KCs中細胞的增殖[90]。

告訴我們:
皮膚表面也可以產生自噬作用
自噬調節角蛋白(上皮角質形成細胞)穩態
IFN-γ,IL-2,誘導自噬。
IFN-γ介導對角質形成細胞的生長抑制。
Th17 cells are characterized by production of IL-17
Th17細胞的特徵在於產生IL-17
IL-2 level was negatively correlated with the level of IL-17A.
IL-2水平與IL-17A水平呈負相關。
In contrast, Th17 cell responses have been shown to be inhibited by IL-2.
相反,已顯示Th17細胞反應被IL-2抑制。
More recently, it was found that IFN-γ inhibits IL-17 production.
最近,發現IFN-γ抑制IL-17的產生。
Our results suggest that IFN-γ inhibits the inflammatory response by downregulating
Th17 cell differentiation and IL-17 production.
我們的結果表明,IFN-γ通過下調Th17細胞分化和IL-17產生來抑制炎症反應。
小結2:
由以上可知,IL-2及IFN-r增加自噬、抑制IL-17的產生、增加調節性T細胞(Tregs),
所以對乾癬是有正面幫助的。
