Insights

This study explores using anti-apoptotic proteins, such as Inhibitor of Apoptosis Proteins (IAP) and BCL2 family proteins, as antigens in therapeutic cancer vaccines. Early trials show promise for harnessing the immune system against cancer.

Area of Science:

  • Immunology
  • Oncology
  • Vaccinology

Background:

  • Cancer research increasingly focuses on leveraging the immune system for treatment.
  • Anti-apoptotic molecules promote cancer cell survival and immune evasion.
  • Spontaneous immune responses against these molecules are observed in cancer patients.

Purpose of the Study:

  • To review Inhibitor of Apoptosis Proteins (IAP) and BCL2 family proteins as T-cell antigens.
  • To present findings from the first exploratory therapeutic vaccination trial using these antigens.
  • To discuss future directions in cancer immunotherapy.

Main Methods:

  • Review of current knowledge on IAP and BCL2 family proteins as T-cell antigens.
  • Conducting an exploratory clinical trial for therapeutic vaccination against cancer.
  • Analysis of immune responses to vaccination.

Main Results:

  • IAP and BCL2 family proteins are identified as viable T-cell antigens for cancer vaccines.
  • The exploratory trial demonstrated the feasibility of therapeutic vaccination using these antigens.
  • Spontaneous immune responses in patients suggest potential for immune system activation.

Conclusions:

  • Therapeutic vaccination using IAP and BCL2 family proteins represents a novel approach in cancer immunotherapy.
  • Further research and clinical trials are warranted to optimize this strategy.
  • Harnessing anti-apoptotic proteins could enhance cancer treatment efficacy.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
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.
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
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...
Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
