MetabolomicsInositol triphosphate-triggered calcium release blocks lipid exchange at endoplasmic reticulum-Golgi contact sites
Vesicular traffic and membrane contact sites between organelles enable the exchange of proteins, lipids, and metabolites. Recruitment of membrane tethers to contact sites between the endoplasmic reticulum (ER) and the plasma membrane is often triggered by calcium. In contrast, we reveal here a funct...

MetabolomicsControlling mitochondrial membrane architecture via MIC60 determines viral replication to promote anti-viral immunity
Virus-infected cells often exhibit dramatic cellular changes accompanied by altered mitochondrial function. The contribution of factors shaping the inner mitochondrial membrane (IMM) and cristae architecture on viral replication is insufficiently understood. Single cell transcriptomics applying vesi...

TranscriptomicsNickel-induced contact dermatitis induce changes in human skin transcriptome over 96 hours
We aimed to characterize transcriptomic changes over time (baseline, 2 hours, 48 hours and 96 hours) after nickel-induced contact dermatitis in 6 human probands. As a contrast, 7 patients with SLS-induced irritant contact dermatitis were included. Therefore, the patch tests were applied onto the bac...

TranscriptomicsDirect contact with mesenchymal stromal cells impacts CD133+ hematopoietic stem cells during ex-vivo expansion
Direct contact with mesenchymal stromal impacts on migratory behavior and gene expression profile of CD133+ hematopoietic stem cells during ex-vivo expansion Objective: To investigate the impact of direct contact between mesenchymal stromal cells (MSCs) and CD133+ hematopoietic stem cells (HSCs) in ...

ProteomicsContact-ID, a new tool for profiling organelle-membrane contact sites, reveals regulatory proteins of mitochondrial-associated membrane formation
The mitochondria-associated membrane (MAM) has emerged as a cellular signaling hub regulating various cellular processes. However, its molecular components remain unclear owing to lack of reliable methods to purify the intact MAM proteome in a physiological context. Here, we introduce Contact-ID, a ...

MetabolomicsSeipin Governs Caveolin-1 Trafficking Through Modulating Sphingolipid-Glycerolipid Balance

Dysregulation of Caveolin-1 (CAV1), a key component of caveolae, leads to pleiotropic disorders; yet, the mechanisms controlling its trafficking remain unclear. Here, we show that the lipid droplet (LD) biogenesis factor seipin controls CAV1 localization. Seipin deficiency in mice and HeLa cells ...

ProteomicsAPEX2 proximity labeling of PI(3)P dependent ER and early endosome membrane contact tether proteins
To understand the nature of ER and early endosome membrane contact site, we capitalized the MTM1 knock out (KO) HeLa cells that do not dissociate the ER and early endosome membrane contact upon nutrient starvation. By using the Doxycyclin inducible APEX2 fused Rab5A (early endosome marker) expressin...

ProteomicsProfiling the LAM family of contact-site tethers provides mechanistic insights into their regulation and function
Membrane contact sites are molecular bridges between organelles that are sustained by tethering proteins and enable organelle communication. The endoplasmic reticulum (ER) membrane harbors many distinct families of tether proteins that enable the formation of contacts with all other organelles. One ...

ProteomicsIdentification of MOSPD2, a novel scaffold for endoplasmic reticulum membrane contact sites
Membrane contact sites are cellular structures that mediate inter-organelle exchange and communication. The endoplasmic reticulum (ER), which forms a network extending throughout the cytoplasm, possesses two known major tether proteins, named VAP-A and VAP-B, that allow its interaction with other or...
