Globally, HCC is the sixth most prevalent cancer and the third-most prevalent reason for neoplastic disease-related deaths. A diverse array of infiltrating immunocytes regulates the development and progression of HCC, as is the case in many other cancers. An understanding of the various immune components during HCC becomes necessary so that novel therapeutic strategies can be designed to combat the disease. A dysregulated immune system(including changes in the number and/or function of immune cells, cytokine levels, and the expression of inhibitory receptors or their ligands) plays a key role in the development of HCC. Alterations in either the innate or adaptive arm of the immune system and cross-talk between them make the immune system tolerant to tumors, leading to disease progression. In this review, we have discussed the status and roles of various immune effector cells(e.g., dendritic cells, natural killer cells, macrophages, and T cells), their cytokine profile, and the chemokine-receptor axis in promoting or impeding HCC.展开更多

Defying the categorical rules used to distinctly characterize lymphocytes as either innate or adaptive in nature, 76 T cells inhabit a hybrid world of their own. At opposing ends of the simplified spectrum of modes of antigen recognition used by lymphocytes, natural killer and ap T cells are particularly well equipped to respond to the 'missing self' and the 'dangerous non-self', respectively. However, between these two reductive extremes, we are chronically faced with the challenge of making peace with the 'safe non-self' and dealing with the inevitable 'distressed self', and it is within this more complex realm 76 T cells excel thanks to their highly empathetic nature. This review gives an overview of the latest insights revealing the unfolding story of human 76 T cells, providing a biographical sketch of these unique lymphocytes in an attempt to capture the essence of their fundamental nature and events that influence their life trajectory. What hangs in their balance is their nuanced ability to differentiate the friends from the foe and the pathological from the benign to help us adapt swiftly and efficiently to life's many stresses.展开更多

The question whether neurodegeneration in MS is independent or related to neuroinflammation has been long debated, but not yet fully clarified. Furthermore, little is still known on how neuroinflammation and neurodegeneration in MS are related to potential regenerative processes. In this perspective, we briefly discuss main clinical, pathological and experimental evidence on the relationship between neuroinflammation and neurodegeneration in MS, and on their connection with regeneration. We discuss that these processes in MS might represent intercorrelated manifestations of the immune response, especially of the innate immunity.展开更多
