Tumor Immunotherapy01:27

Tumor Immunotherapy

2.5K
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.

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.0K
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...

Cancer Therapies

8.5K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.3K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Vaccines01:30

Cancer Vaccines

1.3K
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Area of Science:

  • Oncology
  • Immunology
  • Vascular Biology

Context:

  • Immunotherapies are a promising cancer treatment strategy.
  • Abnormal tumor vasculature creates a hypoxic and immunosuppressive microenvironment, hindering immune cell function.
  • This immunosuppressive environment impedes the efficacy of current cancer immunotherapies.

Purpose:

  • To discuss the impact of vascular normalization on tumor immunity.
  • To propose a strategy for re-engineering the tumor-immune microenvironment.
  • To enhance the effectiveness of cancer immunotherapy.

Summary:

  • Abnormal tumor vasculature leads to a hypoxic microenvironment that suppresses immune responses.
  • Vascular normalization, achieved through anti-angiogenesis, can counteract this immunosuppression.
  • Re-engineering the tumor-immune microenvironment by normalizing vasculature can improve immunotherapy outcomes.

Impact:

  • Vascular normalization presents a potential strategy to overcome treatment resistance in cancer immunotherapy.
  • This approach could lead to improved patient responses and better clinical outcomes.
  • Understanding the interplay between tumor vasculature and immunity is crucial for advancing cancer therapy.
