In addition, factors such as immunosuppressive tumor microenvironment (TME) induced by infiltration of immunosuppressive cells and/or upregulated expression of immune checkpoints, cancer cell heterogeneity, and lack of antigen presentation can suppress the efficacy of cancer immunotherapy [15,16]. Therefore, improving treatment efficacy and reducing the side effects of cancer immunotherapy are critically important.

Tumor microenvironment (TME)

The type of adaptive immunity in which T cells destroy virus-infected or cancer cells is -mediated immunity.

Tumours that have efficiently down regulated the expression of MHC molecules can still get cleared by which of these cells Group of answer choices CD4 T cells CD8 T cells NK cells T regulatory cells

what are Immune Checkpoints? are they proteins on immune cells like white blood cells? what is their function in immune system and how do they work?

Desensitization immunotherapy administers allergen in controlled amounts and stimulates T regulatory cell populations. Which of the following is not a correct statement about this therapy?ANSWERRegulatory T cells stimulate T helper 1 cells.The level of IgG is increased as a result of the desensitization immunotherapy.As a result of the controlled injection of the allergen, the number of IgE molecules is increased.Regulatory T cells discourage T helper 2 cell activity.
