Resumen :
El carcinoma hepatocelular (CHC) es la neoplasia de hígado más común y la esteatohepatitis no alcohólica (EHNA) se ha convertido en la causa de cirrosis hepática y CHC que más ha crecido en la última década a nivel mundial. El sistema inmunitario juega un papel crucial en la patogénesis del CHC y s...  Ver más
Hepatocellular carcinoma (HCC) is the most common liver neoplasia and non-alcoholic steatohepatitis (NASH) has become the fastest growing cause of liver cirrhosis and HCC in the last decade worldwide. The immune system plays a crucial role in the pathogenesis of HCC and it is known that the Western diet, which is rich in fat and salt (NaCl), is a potential disruptor of the physiological functioning of the immune system. In this Master Thesis, the influence of NaCl on Th1 and Th1/Th17 lymphocyte differentiation in mouse models of NASH and HCC has been studied. In parallel, the influence of the presence of fatty acids on the lymphocyte microenvironment has been investigated, studying also the effect of linoleic acid and palmitic acid on the differentiation of CD4+ lymphocytes. The results obtained point to the fact that a high salt diet (HSD) induces differentiation to Th1 and Th1/Th17 lymphocytes, as well as increased production of IFNγ. Mice fed a HSD developed fewer and smaller tumors in comparison with the control group. It has also been observed that linoleic acid promotes the differentiation of the Th1 profile, whereas palmitic acid does not seem to have any effect on this population, suggesting that lipid composition can modulate the T cell response.
