Summary
Lichen planopilaris (LPP) involves altered integrin distribution in hair follicles, leading to easy hair removal. This study investigated integrin expression in active LPP lesions.
Area of Science:
- Dermatology
- Cell Biology
- Hair Follicle Biology
Background:
- Lichen planopilaris (LPP) is an inflammatory scalp condition causing scarring alopecia.
- Active LPP features easy hair plucking with anagen-like roots.
- The study investigates integrins and basement membrane components in LPP.
Purpose of the Study:
- To examine the expression and distribution of integrins and basement membrane components in active Lichen planopilaris lesions.
- To understand the cellular mechanisms behind hair follicle changes in LPP.
Main Methods:
- Scalp biopsies from 10 LPP patients and 5 healthy controls.
- Immunohistochemical analysis using monoclonal antibodies against alpha3beta1 and alpha6beta4 integrins.
- Comparison of integrin expression in lesional LPP scalp versus healthy scalp skin.
Main Results:
- Alpha3beta1 integrin showed a pericellular distribution in LPP-affected areas.
- Alpha6 integrin exhibited basolateral distribution.
- Beta4 integrin displayed discontinuous basal pole expression and occasional basolateral staining in the hair follicle.
Conclusions:
- Altered integrin distribution in active LPP contributes to the characteristic easy hair removal.
- The findings provide insights into the pathogenesis of hair follicle abnormalities in LPP.
- Understanding these changes may inform future therapeutic strategies for LPP.

00:55Laminins are the Adhesive Proteins of Basal Lamina
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

01:17Intracellular Signaling Affects Focal Adhesions
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

01:10Integrins
Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

01:15Activation of Integrins
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.

01:25Selectins
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
01:03Anchoring Junctions
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...
