Planktonic Archaeal Ether Lipid Origins in Surface Waters of the North Pacific Subtropical Gyre

open access: yesFrontiers in Microbiology, 2021
Thaumarchaeota and Thermoplasmatota are the most abundant planktonic archaea in the sea. Thaumarchaeota contain tetraether lipids as their major membrane lipids, but the lipid composition of uncultured planktonic Thermoplasmatota representatives remains ...

Distribution and abundance of tetraether lipid cyclization genes in terrestrial hot springs reflect pH.

open access: yesEnvironmental Microbiology, 2023
Many Archaea produce membrane-spanning lipids that enable life in extreme environments. These isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) may contain up to eight cyclopentyl and one cyclohexyl ring, where higher degrees of cyclization ...

Structure-function relationships in pure archaeal bipolar tetraether lipids. [PDF]

open access: yesChem Sci, 2023
A series of archaeal bipolar glycerol dialkyl glycerol tetraether (GDGT) lipids were synthesized. Structural properties of self-assembled structures of GDGTs were studied and related to functional behavior such as membrane fusion.

Tracing tetraether lipids from source to sink in the Rhône River system (NW Mediterranean) [PDF]

open access: gold, 2015
In this study, we investigated soils and river suspended particulate matter (SPM) collected in the Rhône and its tributary basins as well as marine surface sediments taken in the Rhône prodelta (Gulf of Lions, NW Mediterranean).

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Drastic changes in the distribution of branched tetraether lipids in suspended matter and sediments from the Yenisei River and Kara Sea (Siberia): Implications for the use of brGDGT-based proxies in coastal marine sediments [PDF]

open access: green, 2015
The distribution of branched glycerol dialkyl glycerol tetraethers (brGDGTs) in soils has been shown to correlate with pH and mean annual air temperature.

Depth-related distribution of a key gene of the tetraether lipid biosynthetic pathway in marine Thaumarchaeota. [PDF]

open access: yesEnvironmental Microbiology, 2015
The distribution of isoprenoid glycerol dialkyl glycerol tetraethers (GDGT) lipids synthesized by Thaumarchaeota has been shown to be temperature-dependent in world oceans.

Overcoming the Mucosal Barrier: Tetraether Lipid‐Stabilized Liposomal Nanocarriers Decorated with Cell‐Penetrating Peptides Enable Oral Delivery of Vancomycin

open access: yes, 2021
Despite the high medical need for oral peptide delivery, instability in the gastrointestinal tract and low mucosal permeation still impede this preferred route of administration.

The influence of near surface sediment hydrothermalism on the TEX86 tetraether lipid-based proxy and a new correction for ocean bottom lipid overprinting

open access: yesBiogeosciences, 2021
. The diversity and relative abundances of tetraether lipids produced by Thaumarchaeota in soils and sediments increasingly is used to assess environmental change.

Improvement of Pulmonary Photodynamic Therapy: Nebulisation of Curcumin-Loaded Tetraether Liposomes

open access: yesPharmaceutics, 2021
Lung cancer is one of the most common causes for a high number of cancer related mortalities worldwide. Therefore, it is important to improve the therapy by finding new targets and developing convenient therapies.
