We then use a skin model to visualize the mechanism of this protection. The excitement came from finding that blocking the circadian clock repositions neutrophils right into the injury zone - thereby sparing the healthy tissue from the cytotoxicity of neutrophils

We uncover a circadian “checkpoint” in neutrophils that naturally reduces inflammation by targeting their intrinsic circadian clock! Activating CXCR4 represses circadian-related activation of neutrophils, critically reducing inflammatory injury to the infarcted heart

Today, we see the fruit of 5+ years of teamwork. We have built a map of the neutrophil compartment (mostly in mice - but also humans). It provides a biological structure that focuses on a single immune cell lineage to discover the many ways in which neutrophils "interpret" physiology.

Immune cells are more than aggressors; they are also diplomats that prevent conflict by improving the barrier capacity, the ECM, and the mechanical properties of tissues. We are just beginning to scratch the true impact of immune cells on tissues and overall organismal physiology.

A final take-home message: In biology, cells are not what they look but what they do. Cell lineages are human divides, and the remarkable plasticity of myeloid cells teaches us that biology works by instructing functional programs at defined times and places.

Andres Hidalgo @drusqui.bsky.social · 19/03/2025
You can find a lot more details, controls and ideas in the paper With @alazozcan.bsky.social can we are now exploring if this unconventional matrigenic capacity of immune cells matters in other physiological and pathological contexts… stay tuned for more surprises!

When we created a small wound in the skin, matrix-producing neutrophils would rapidly accumulate around the lesion to build matrix "rings" that protected from small molecules or microbes… magical images from the hands of the master of microscopy Uderhardt and @alazozcan.bsky.social

We interpret that neutrophils complement fibroblasts with their unique migratory properties, and capacity to reach places other cells can’t.

Andres Hidalgo @drusqui.bsky.social · 19/03/2025
We propose that what is unique to neutrophils is their capacity to dynamically reinforce the matrix: the skin becomes stiffer at night-time, when neutrophils enter the tissue! An experiment from the mind and hands of @TVicanolo !

Andres Hidalgo @drusqui.bsky.social · 19/03/2025
To demonstrate this, we generated a reporter mouse in which collagens produced by neutrophils (or fibroblasts, for comparison) are labeled with mCherry. Amazing craft by @alazozcan.bsky.social to set this up...

Andres Hidalgo @drusqui.bsky.social · 19/03/2025
But how do neutrophil mediate this unexpected property of the skin? Although questions remain, we find that they are uniquely specialized in depositing matrix components, such as Collagen 3, in specific areas of the skin where large matrix fibers provide mechanical reinforcement to the skin

Andres Hidalgo @drusqui.bsky.social · 19/03/2025
An exciting finding was that neutropenic mice, or mice lacking TGF signaling in neutrophils, both have major alterations in the skin: matrix structure, composition and skin mechanics are dramatically altered, resulting in a more permeable skin

Andres Hidalgo @drusqui.bsky.social · 19/03/2025
We report that neutrophils from the skin (and other epithelial barriers) are unique. They produce matrix components, including collagens and enzymes that remodel the matrix. This program, induced through TGFb signaling, is shared by mice and humans.
