Abstract:
Concanavalin A (Con A)-induced hepatitis has been investigated as a model of T cell-mediated liver injury, in which IFN-gamma plays an essential role by inducing apoptosis of liver cells. Since a large number of neutrophils infiltrate into the liver in the model, the role of neutrophils was investigated in this study. Con A hardly caused liver injury in neutrophil-depleted mice, as assessed as to the plasma alanine aminotransferase level as well as histochemistry. Neutrophil-depleted mice also failed to produce IFN-gamma. Intracellular IFN-gamma staining revealed that, among liver leukocytes, T and NK cells but not neutrophils are the main producers of IFN-gamma. Nylon wool-purified "T cells", however, failed to produce IFN-gamma in response to Con A in vitro, while the production was restored by the addition of neutrophils. Overall, this study suggests that neutrophils play a novel accessory role in IFN-gamma production in Con A-induced hepatitis.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
