Major Highlights of the Research
Molecular Assembly:
- Scientists assembled lysozyme molecules into a 2D monolayer at the interface of a pure water subphase.
Model for Amyloidosis:
- The arranged layers of lysozyme provide a unique model for investigating the complexities of Amyloidosis.
Langmuir-Blodgett Technique:
- Utilized the Langmuir-Blodgett (LB) technique to create specialized two-dimensional protein layers.
- This technique involves forming monolayers of molecules, including proteins, at air-water and air-solid interfaces.
pH-Dependent Changes:
- Observed changes in the structure and shape of lysozyme molecules under different pH conditions.
- These changes mirror abnormalities seen in Amyloidosis.
Research Significance:
- Offers deeper insights into Amyloidosis, contributing to a better understanding of disease mechanisms.
- Establishes a versatile platform for exploring nanotechnology applications in protein science.
Lysozyme:
- Lysozyme is a naturally occurring enzyme present in bodily secretions such as tears, saliva, and mucus.
Defensive Role:
- Plays a vital role in the body’s defense system by combating bacteria.
- Acts by breaking down the cell walls of specific bacteria, disrupting their structure and leading to destruction.
Airway Fluid Component:
- Principal component of airway fluid.
- Serves as a model protein in the study of diseases like Amyloidosis, associated with multi-organ dysfunction.
Amyloidosis
- Amyloidosis encompasses a set of uncommon disorders marked by the buildup of anomalous protein aggregates known as amyloids in diverse organs and tissues across the body.
- Comprising misfolded proteins, these amyloid formations can interfere with the regular functioning of organs such as the heart, kidneys, liver, and spleen, leading to gradual damage over time.
