You might’ve heard about the #BBB but have you heard about the BNB (Blood Nerve Barrier)? #pns #bloodnervebarrier
We showed that endoneurial blood vessels (EndoBVs) are surrounded by pericytes (alphaSMA, orange) 🤗 @ImarisSoftware

9) Many risk factors modulate the propensity of LDL-C to traverse the endothelium and enter the arterial intima. See 🔓academic.oup.com/eurheartj/arti….
10) It now appears that the passage of #LDL into the #intima is not a merely passive process whereby the concentration in blood & the permeability of the endothelium determine LDL accumulation.
11) It’s #Transcytosis (an active process), through a vesicular pathway involving #caveolae, scavenger receptors (#SRB1) and activin like receptor kinase 1 (#ALK1). Hence for a given blood level of LDL-C the amount of atherosclerosis is variable.

How long do #neutrophils live? Are they all equal or do they adapt to tissues?

Neutrophils are almost ubiquitous in the body. At varying levels, but present in almost every tissue
This is a finding in line with our previous work by @Casanova_Acebes @NicolasAvilaJA & Jackson Li @JExpMed 2018
We found unique breast immune cells in the duct walls – ductal macrophages. They remove dying cells, help remodelling + are key players in cancer.
How did we get from this first sighting to finding their identity and function? Follow this thread!

The breast contains mammary ducts surrounded by fat, blood vessels, immune + other cells.
We use 3D imaging to investigate the complex relationships b/w these cells to better understand disease.

The ducts form a tree that branches through the breast and blooms and recedes in pregnancy and weaning. These are precancerous mouse ducts, alveoli in lactation and a summary of development in mice.

Extracellular acidity in atherosclerosis is one of my favorite topics, so I'm really, really excited about this study (2/15)
The authors show that some individuals have carotid atherosclerotic lesions that have an acidic pH. They show this is due to activation of Na+-H+ exchanger in macrophages, which leads to extrusion of H+ and extracellular acidification (3/15)

#Tweetorial time! 🚨 Looks like there’s another misconception about #cholesterol and #atherosclerosis making rounds again. This one has to do with the process of #LDL particles entering the arterial wall. So gather round friends and let me science the s*it out of this 🤓 (1/24)
For background, here’s a widely cited series of figures by Nakashima et al. (2007). They performed autopsies on 38 people aged 7-49, who died of non-#cardiovascular causes (2/24)

Nakashima et al. looked for atherosclerotic lesions at different stages, according to a previously published morphological classification scheme. They found them, took slices, stained them to find #lipids and #macrophages and organized them nicely (3/24)
Wow this is major 👉 In simple terms, infection can change the #electrical properties of #macrophages in a way that eventually directs the white blood cells away from the site of #infection...allowing the escape of the macrophages that contain pathogens
Also, remember this study? 👉 which found that #bacteria in #biofilm communities not only coordinate their own behavior, but also influence the behavior of diverse species at a distance☝️via ion channel mediated long-range electrical signaling: ncbi.nlm.nih.gov/pmc/articles/P…
And this study 👉 which found that #bacteria in the human gut can generate #electricity☝️The genes that code for this electrical transfer were identified in hundreds of bacterial species, including human pathogens: nature.com/articles/s4158…
