The Tumor Microenvironment02:17

The Tumor Microenvironment

7.2K
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...

Differentiation of Common Myeloid Progenitor Cells

3.6K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Regulation of Hematopoietic Stem Cells

3.6K
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...

Area of Science:

  • Hematology
  • Oncology
  • Immunology

Background:

  • Chronic inflammation is a key characteristic of myeloproliferative neoplasms (MPNs).
  • Elevated proinflammatory cytokines are present in all MPN subtypes.
  • Systemic inflammation contributes to MPN symptoms, thrombosis, atherosclerosis, and disease progression.

Purpose of the Study:

  • To describe the inflammatory milieu in MPN.
  • To explore the role of soluble factors and cellular mediators in MPN inflammation.
  • To discuss the prognostic value of cytokine measurements and potential targeted therapies.

Main Methods:

  • Review of the inflammatory milieu in MPN.
  • Analysis of soluble factors and cellular mediators.
  • Discussion of prognostic value and therapeutic strategies.

Main Results:

  • Neoplastic cells and their progeny drive inflammation in MPN.
  • Nonmalignant cells also contribute to cytokine secretion.
  • Cytokine levels and cellular mediators define the inflammatory landscape in MPN.

Conclusions:

  • The inflammatory milieu is crucial in MPN pathogenesis and progression.
  • Cytokine measurements hold prognostic value for MPN patients.
  • Targeting cellular inflammation mediators presents a promising therapeutic avenue for MPNs.
