Abnormal Proliferation02:23

Abnormal Proliferation

4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Antigen Presenting Cells

1.9K
The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

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.
Naive T cells that have not yet encountered an antigen express two primary CD...

Area of Science:

  • Immunology
  • Hematology
  • Oncology

Background:

  • Plasmacytoid dendritic cells (pDCs) are key immune modulators, producing type I interferons.
  • pDC neoplasms are broadly classified into mature pDC proliferation (MPDCP) and blastic pDC neoplasm (BPDCN).
  • MPDCP is linked to chronic myelomonocytic leukemia, while BPDCN is an aggressive malignancy affecting multiple organs.

Purpose of the Study:

  • To provide a comprehensive review of pDC neoplasms.
  • To detail the characteristics and immunophenotype of BPDCN.
  • To discuss current and emerging therapeutic strategies for BPDCN.

Main Methods:

  • Literature review of pDC neoplasms.
  • Analysis of clinical and pathological features of BPDCN.
  • Summary of treatment modalities, including historical and novel targeted agents.

Main Results:

  • BPDCN presents with diverse skin lesions and involves skin, bone marrow, lymphatic organs, and CNS.
  • Typical BPDCN immunophenotype includes CD4, CD56, CD123, and specific pDC markers.
  • Treatment historically involved acute leukemia regimens and transplantation; targeted therapies are emerging.

Conclusions:

  • BPDCN is a distinct and aggressive myeloid malignancy.
  • Understanding the immunophenotype is crucial for BPDCN diagnosis.
  • Targeted therapies, particularly those against CD123, show promise for BPDCN treatment.
