The use of interferons in anti-cancer therapy is justified by the experimental evidence that these cytokines are able to enhance in vitro the expression of some surface molecules such as major histocompatibility complex and tumor associated lymphocytes. Furthermore, a synergism of action of interleukin-2 with alpha-interferon in the treatment of human malignancies has been described. Nevertheless, whether the in vivo role of interferons associated to interleukin-2 as anti-cancer drugs is actually related to the properties of this cytokine of modulating surface molecule expression on target cells, has never been clearly reported. In this report, we describe an immune system cell resetting, during immunotherapy with interleukin-2 plus alpha-interferon, which seems to support this hypothesis.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
