Insights

Epidermal growth factor receptor (EGFR) blockade in cancer patients can cause acne-like skin issues. This occurs due to EGFR

Area of Science:

  • Dermatology
  • Oncology
  • Molecular Biology

Background:

  • Acne-like skin eruptions are a common side effect of EGFR inhibitor cancer therapies.
  • These eruptions are characterized by sterile inflammation.

Purpose of the Study:

  • To explore the mechanisms behind EGFR inhibitor-induced acneiform eruptions.
  • To investigate the role of EGFR signaling in hair follicle inflammation.

Main Methods:

  • Discussion of pathogenic mechanisms.
  • Focus on EGFR blockade in outer root sheath keratinocytes.
  • Analysis of interleukin-1-dependent inflammatory networks.

Main Results:

  • EGFR signaling appears to restrain inflammatory mediators.
  • EGFR blockade may disrupt the control of inflammation at the hair follicle.

Conclusions:

  • EGFR plays a role in regulating inflammatory responses in the hair follicle.
  • Understanding this mechanism could lead to better management of skin toxicities in cancer patients.

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
