Sir2 regulates selective autophagy in stationary-phase yeast cells
January 21, 2026
This study establishes Sir2 as a previously unrecognized regulator of selective autophagy during the stationary phase and highlight how cells dynamically control organelle degradation.
A complex remodeling of cellular homeostasis distinguishes RSV/SARS-CoV-2 co-infected A549-hACE2 expressing cell lines
October 8, 2024
Given the common tropism of SARS-CoV-2 and RSV, and the unclear consequences of their mutual influence, we developed an in vitro lung epithelial cell model to study the molecular mechanisms and cellular pathways modulated in viral co-infection.
Atg1, a key regulator of autophagy, functions to promote MAPK activation and cell death upon calcium overload in fission yeast
May 10, 2023
Here, we provide evidence that the fission yeast Atg1 regulates cell death responses upon intracellular calcium load in addition to its role in promoting Pmk1 MAPK.
Plant and fungal products that extend lifespan in Caenorhabditis elegans
July 9, 2020
Caenorhabditis elegans' lifespan is extended by plant and fungal extracts activating pathways like autophagy and mitochondrial biogenesis. Low to moderate concentrations promote longevity, while high doses are harmful. This review explores the health benefits of these substances in humans.
Regulation of anti-microbial autophagy by factors of the complement system
March 19, 2020
This review explores emerging evidence that components of the complement system, beyond their traditional immune roles, modulate autophagy - particularly xenophagy - thereby influencing cell-autonomous antimicrobial responses during host-pathogen interactions.
Temporal analysis of the autophagic and apoptotic phenotypes in Leishmania parasites
August 1, 2018
This article details a comprehensive analysis of miltefosine-induced cell death and autophagy in Leishmania major, providing criteria for clear identification of apoptotic and autophagic cells, demonstrating the sequential nature of autophagy followed by apoptosis in nutrient-deprived conditions, and cautioning against using the generic kinase inhibitor staurosporine as a Leishmania apoptosis inducer, with the aim of improving the understanding of these processes and their targeting for new anti-leishmanial drugs.
Endolysosomal pathway activity protects cells from neurotoxic TDP-43
March 21, 2018
In this article, the authors comment on the study "TDP-43 controls lysosomal pathways thereby determining its own clearance and cytotoxicity" by Leibiger et al. (Hum Mol Genet, 2018), proposing that ameliorating endolysosomal pathway activity enhances cell survival in TDP‑43-associated diseases.
New perspectives from South-Y-East, not all about deathA report of the 12th lnternational Meeting on Yeast Apoptosis in Bari, Italy, May 14th-18th, 2017
January 16, 2018
In this article Guaragnella et al. report on the 12th International Meeting on Yeast Apoptosis (IMYA12), which was held in Bari, Italy from May 14th to 18th, 2017, where more than 100 participants, among which senior and young scientists from Europe, USA, North Africa and Japan, had an intense and open exchange of achievements and ideas in the field of yeast regulated cell death (RCD).
Guidelines and recommendations on yeast cell death nomenclature
January 1, 2018
In this review, we propose unified criteria for the definition of accidental, regulated, and programmed forms of cell death in yeast based on a series of morphological and biochemical criteria. Specifically, we provide consensus guidelines on the differential definition of terms including apoptosis, regulated necrosis, and autophagic cell death, as we refer to additional cell death routines that are relevant for the biology of yeast.
Targeting GATA transcription factors – a novel strategy for anti-aging interventions?
May 6, 2019
This article comments on work published by Carmona-Gutierrez et al. (Nat Commun., 2019), which identified a natural compound, 4,4'-dimethoxychalcone, inducing autophagy and prolonging lifespan in different organisms through a mechanism that involves GATA transcription factors.
