Abstract Background The tumor immunological microenvironment (TIME) has a prominent impact on prognosis and immunotherapy. However, the heterogeneous TIME mechanisms by which affects immunotherapy have not been elucidated in hepatocellular carcinoma (HCC). Methods A total of 2195 eligible HCC patients from TCGA GEO database were collected. We comprehensively explored different phenotypes its cl...

gene association studies are less appealing in cancer compared to autoimmune diseases. complexity, heterogeneity, variation in histological types, age at onset, short survival, and acute versus chronic conditions are cancer related factors which are different from an organ specific autoimmune disease, such as grave’s disease, on which a large body of multicentre data is accumulated. for years t...

a total of 240 ross 308 day-old male broiler chicks within a completely randomized design were used in this experiment to evaluate the effects of dietary inclusion of turmeric powder and cinnamon powder on performance and some immune responses of broiler chickens. dietary treatments were as follow: a corn-soybean meal basal diet (control); basal diet + 10 ppm avilamycin; basal diet + 2.5 g/kg t...

background & aim: continuous use of antibiotics leads to drug resistance and thereby to a reduced efficacy of the drugs. antibiotics accumulate in the environment and fish pose a potential risk to consumers and to the environment.increased public awareness of the negative effects caused by overexposure to synthetic chemicals has led to the search for ‘‘green drugs’’, such as organic and syn...

background and aims:il-22 is an α-helical cytokine.il-22 binds to a heterodimeric cell surface receptor composed of il-10r2 and il-22r1subunits.il-22r is expressed on tissue cells and it is absent on immune cells.il-22 and il-10 receptor chains play a role in cellular targeting and signal transduction to selectively initiate and regulate immune responses. the aim of this study was to investigat...

obesity is characterized as a state of systemic low-grade inflammation suggesting a link between metabolism and immune function. obesity has been shown to predispose individuals to an increased risk of many diseases.since 1980s, a threefold increase in obesity has been reported in much of the world.obesity is a result of energy imbalance. one of the components that control energy balance is adi...

The concept of tumor immune surveillance has been supported by several recent studies in mice which show that immune effector mechanisms suppress hematologic malignancy. However, because the most common forms of human cancer are epithelial in origin, and comparatively very little data supports the immune surveillance of epithelial malignancies, we have chosen to evaluate the role of perforinmed...

T cell priming is a critical event in the initiation of the immune response to vaccination since it deeply influences both the magnitude and the quality of the immune response induced. CD4(+) T cell priming, required for the induction of high-affinity antibodies and immune memory, represents a key target for improving and modulating vaccine immunogenicity. A major challenge in the study of in v...

The adaptive immune system is expected to protect the host from infectious agents and malignancies, while avoiding robust activation against self-peptides. However, T cells are notoriously inept at protection whenever the pathogen or tumor is persistent in the body for longer periods of time. While this has been thought of as an adaptation to limit the immunopathology from continued effector T-...
