If phosphatidylserine is the death knell, a new phosphatidylserine-specific receptor is the bellringer [PDF]

Cell Death & Differentiation, 2001
Recognition of phosphatidylserine (PtdSer) is essential for engulfment of apoptotic cells by mammalian phagocytes. Engagement of a new phosphatidylserine-specific receptor (PtdSerR) appears to be necessary for uptake of apoptotic cells. Many other mammalian receptors have been described to function in the clearance of apoptotic cells.

Nanoscopic Spatial Association between Ras and Phosphatidylserine on the Cell Membrane Studied with Multicolor Super Resolution Microscopy

Biomolecules, 2022
Recent work suggests that Ras small GTPases interact with the anionic lipid phosphatidylserine (PS) in an isoform-specific manner, with direct implications for their biological functions.

Expression of phosphatidylserine (PS) on wild-type and Gerbich variant erythrocytes following glycophorin-C (GPC) ligation [PDF]

, 2005
Glycophorin-C (GPC) is a 40 kDa glycoprotein expressed on erythrocytes and is a receptor for the malarial parasite Plasmodium falciparum to invade these cells.

Functional consequences of sphingomyelinase-induced changes in erythrocyte membrane structure [PDF]

, 2012
Contains fulltext : 107961.pdf (Publisher’s version ) (Open Access)Inflammation enhances the secretion of sphingomyelinases (SMases). SMases catalyze the hydrolysis of sphingomyelin into phosphocholine and ceramide.

Hemagglutinating activity of phosphatidylserine [PDF]

FEBS Letters, 1983
In [l] we reported the structure and hemagglutinating activity of an ornithine-containing lipid of Bordetella pertussis. The proposed structure of the aminolipid is 3-hydroxyhexadecanoic acid amide-linked to ornithine and esterified to the second hexadecanoic acid. The aminolipid strongly agglutinated human and rabbit erythrocytes. Here, I describe the

Tim-4 in Health and Disease: Friend or Foe?

Frontiers in Immunology, 2020
T-cell immunoglobulin and mucin domain containing 4 (Tim-4) is a phosphatidylserine receptor and is selectively expressed on antigen presenting cells. Recently, Tim-4 was reported to be expressed on iNKT cells, B1 cells, and tumor cells, suggesting it ...

New sensitive assay for phosphatidylserine decarboxylase based on the detection of CO2 from nonradiolabeled phosphatidylserine [PDF]

, 1973
A new rapid assay for phosphatidylserine decarboxylase, which is sensitive in the nanomolar range, is described. Synthesis of radiolabeled phosphatidylserine for use as a substrate is not required, since the assay, unlike previous ones, is based on the ...

Fluoxetine Induced Suicidal Erythrocyte Death

Toxins, 2013
The antidepressant fluoxetine inhibits ceramide producing acid sphingomyelinase. Ceramide is in turn known to trigger eryptosis the suicidal death of erythrocytes characterized by cell shrinkage and exposure of phosphatidylserine at the erythrocyte ...
