Intracellular Signaling Affects Focal Adhesions

Intracellular 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.

Area of Science:

Ophthalmology
Medical Imaging
Retinal Diseases

Background:

Focal choroidal excavation (FCE) is a rare condition affecting the choroid.
Choroidal neovascular membrane (CNVM) is a common cause of vision loss.
Spectral-domain optical coherence tomography (SD-OCT) is crucial for visualizing these pathologies.

Observation:

This case series presents four patients with FCE.
Imaging characteristics of FCE and associated CNVM were analyzed using SD-OCT.
FCE was observed as an acquired condition post-CNVM treatment in two patients.
FCE was pre-existing in the other two patients.

Findings:

SD-OCT revealed distinct imaging features of FCE.
The study observed both acquired and pre-existing FCE.
A strong association between FCE and the pachychoroid spectrum was reaffirmed.

Implications:

Understanding FCE's imaging characteristics aids diagnosis.
The findings suggest potential etiopathogenesis pathways for FCE.
This reaffirms the link between FCE and pachychoroid diseases, guiding further research.
