Over the course of time, Hepatitis C has become a universal health menace. Its deleterious effects on human liver encompass a lot of physiological, genetic as well as epigenetic alterations. Fatty liver (Hepatic steatosis) is an inflammation having multifactorial ancestries; one of them is HCV (steatohepatitis). HCV boosts several cellular pathways involving up-regulation of a number of cytokines. Current study reviews the regulation of some selective key cytokines during HCV infection, to help generate an improved understanding of their role. These cytokines, IL-1β, IL-6, TNF-α, and IFN-ϒ, are inflammatory markers of the body. These particular markers along with others help hepatocytes against viral infestation. However, recently, their association has been found in degradation of liver on the trail heading to non-alcoholic steatohepatitis (NASH). Consequently, the disturbance in their equilibrium has been repeatedly reported during HCV infection. Quite a number of findings are affirming their up-regulation. Although these cell markers are stimulated by hepatocytes as their standard protection mechanism, but modern studies have testified the paradoxical nature of this defense line. Nevertheless, direct molecular or epigenetic research is needed to question the actual molecular progressions and directions commanding liver to steatosis, cirrhosis, or eventually HCC (Hepatocellular Carcinoma).
随着时间的推移,丙型肝炎已成为一种全球性的健康威胁。它对人类肝脏的有害影响包括许多生理、遗传以及表观遗传改变。脂肪肝(肝脂肪变性)是一种具有多因素起源的炎症;其中之一是丙型肝炎病毒(脂肪性肝炎)。丙型肝炎病毒会激活多种细胞途径,包括多种细胞因子的上调。当前的研究回顾了丙型肝炎病毒感染期间一些选择性关键细胞因子的调节情况,以帮助更好地理解它们的作用。这些细胞因子,白细胞介素-1β、白细胞介素-6、肿瘤坏死因子-α和干扰素-γ,是身体的炎症标志物。这些特定的标志物以及其他标志物有助于肝细胞抵抗病毒感染。然而,最近发现它们与非酒精性脂肪性肝炎(NASH)病程中肝脏的退化有关。因此,在丙型肝炎病毒感染期间,它们的平衡失调屡有报道。大量研究结果证实它们上调。尽管这些细胞标志物作为标准保护机制受到肝细胞的刺激,但现代研究证明了这条防线的矛盾性质。然而,需要直接的分子或表观遗传学研究来探究导致肝脏发生脂肪变性、肝硬化或最终肝细胞癌(HCC)的实际分子进程和方向。
