Raft-like lipid microdomains drive autophagy initiation via AMBRA1-ERLIN1 molecular association within MAMs

Manganelli, Valeria ; Matarrese, Paola ; Antonioli, Manuela ; Gambardella, Lucrezia ; Vescovo, Tiziana ; Gretzmeier, Christine ; Longo, Agostina ; Capozzi, Antonella ; Recalchi, Serena ; Riitano, Gloria ; Misasi, Roberta ; Dengjel, Jörn ; Malorni, Walter ; Fimia, Gian Maria ; Sorice, Maurizio ; Garofalo, Tina

In: Autophagy, 2020, p. 1-21

Mitochondria-associated membranes (MAMs) are essential communication subdomains of the endoplasmic reticulum (ER) that interact with mitochondria. We previously demonstrated that, upon macroautophagy/autophagy induction, AMBRA1 is recruited to the BECN1 complex and relocalizes to MAMs, where it regulates autophagy by interacting with raft-like components. ERLIN1 is an endoplasmic reticulum...

Bovine lactoferrin-induced CCL1 expression involves distinct receptors in monocyte-derived dendritic cells and their monocyte precursors

Latorre, Daniela ; Pulvirenti, Nadia ; Covino, Daniela Angela ; Varano, Barbara ; Purificato, Cristina ; Rainaldi, Gabriella ; Gauzzi, Maria Cristina ; Fantuzzi, Laura ; Conti, Lucia ; Donninelli, Gloria ; Del Cornò, Manuela ; Sabbatucci, Michela ; Gessani, Sandra ; Puddu, Patrizia

Lactoferrin (LF) exhibits a wide range of immunomodulatory activities including modulation of cytokine and chemokine secretion. In this study, we demonstrate that bovine LF (bLF) up-modulates, in a concentration- and time-dependent manner, CCL1 secretion in monocytes (Mo) at the early stage of differentiation toward dendritic cells (DCs), and in fully differentiated immature Mo-derived DCs...

Background: The development of a vaccine against HIV/AIDS capable of preventing virus infection has been hampered by the HIV envelope (Env) heterogeneity that makes it difficult to induce neutralizing antibodies against Env proteins from different HIV clades. Several studies have indicated that gp120 Env protein sequence tends to change considerably during the course of HIV disease which...

HUWE1 E3 ligase promotes PINK1/PARKIN-independent mitophagy by regulating AMBRA1 activation via IKKα

Rita, Anthea Di ; Peschiaroli, Angelo ; D?Acunzo, Pasquale ; Strobbe, Daniela ; Hu, Zehan ; Gruber, Jens ; Nygaard, Mads ; Lambrughi, Matteo ; Melino, Gerry ; Papaleo, Elena ; Dengjel, Jörn ; Alaoui, Said El ; Campanella, Michelangelo ; Dötsch, Volker ; Rogov, Vladimir V. ; Strappazzon, Flavie ; Cecconi, Francesco

In: Nature Communications, 2018, vol. 9, no. 1, p. 3755

The selective removal of undesired or damaged mitochondria by autophagy, known as mitophagy, is crucial for cellular homoeostasis, and prevents tumour diffusion, neurodegeneration and ageing. The pro-autophagic molecule AMBRA1 (autophagy/beclin-1 regulator-1) has been defined as a novel regulator of mitophagy in both PINK1/PARKIN-dependent and -independent systems. Here, we identified the E3...
