Summary
Sarah Colijn won the 2020 DMM Prize for her research on RIPK3's role in atherosclerosis. Her work identified cell-specific functions of RIPK3 that protect against this cardiovascular disease.
Area of Science:
- Cardiovascular Biology
- Immunology
- Molecular Mechanisms of Disease
Background:
- Atherosclerosis is a complex cardiovascular disease driven by inflammation and lipid accumulation in artery walls.
- Receptor-interacting protein kinase 3 (RIPK3) is a key mediator of programmed cell death pathways, including necroptosis.
- The precise roles of RIPK3 in atherosclerosis remain incompletely understood, particularly regarding cell-type-specific functions.
Discussion:
- This study investigated the specific roles of RIPK3 in different cell types within the context of a mouse model of atherosclerosis.
- Findings highlight distinct functions of RIPK3 in vascular cells versus immune cells contributing to atherosclerotic plaque development.
- The research elucidates how RIPK3 signaling influences inflammatory responses and cellular fate within the arterial wall.
Key Insights:
- RIPK3 exhibits cell-specific athero-protective functions in a murine atherosclerosis model.
- Targeting RIPK3 in specific cell populations may offer a novel therapeutic strategy for atherosclerosis.
- Understanding RIPK3's complex roles is crucial for developing targeted treatments for cardiovascular diseases.
Outlook:
- Further research is needed to translate these findings into human therapies for atherosclerosis.
- Investigating the upstream regulators and downstream effectors of RIPK3 in atherosclerosis is warranted.
- Exploring the therapeutic potential of modulating RIPK3 activity in distinct cell types could lead to new treatments.

03:22Colloids
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...
01:29Diels–Alder Reaction: Characteristics of Dienes
The Diels–Alder reaction brings together a diene and a dienophile to form a six-membered ring. Both components have unique characteristics that influence the rate of the reaction.
Characteristics of the diene
Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...

01:28Stability of Conjugated Dienes
Introduction
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

01:08Cloning of Dolly the Sheep
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
01:09Colloidal precipitates
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...
01:15Divergence and Curl
The divergence of a vector field at a point is the net outward flow of the flux out of a small volume through a closed surface enclosing the volume, as the volume tends to zero. More practically, divergence measures how much a vector field spreads out or diverges from a given point. For an outgoing flux, conventionally, the divergence is positive. The diverging point is often called the "source" of the field. Meanwhile, the negative divergence of a vector field at a point means that the vector...
