The effect of oral consumption of shark cartilage on the cellular immune responses of cancer patients

Background: Shark cartilage is one of the complementary medicines for cancer patients that inhibits tumor progression by several mechanisms. There is not sufficient evidence on its effects on human immune system thereby we investigated its modulatory effects on some cellular immune response parameters in breast cancer patients. Material and methods: After preparation of shark cartilage powder ...

Specificity of Cellular Immune Responses

In vitro antigen stimulation of DNA synthesis in lymph node cultures from immunized guinea pigs can be obtained with very low (10(-4) microg/ml) antigen concentrations in the culture fluid. Immunization with low doses of DNP-GPA leads to a cell population capable of being stimulated, on the average, by low concentration of antigen whereas immunization with large antigen doses results in a sensi...

An HIV-1 Mini Vaccine Induced Long-lived Cellular and Humoral Immune Responses

Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...
