Hematopoietic stem and progenitor cells as a reservoir for trained immunity

eLife
Human and murine studies reveal that innate immune cells are able to mount enhanced responses to pathogens after primary inflammatory exposure. Innate immune memory has been shown to last for months to years, longer than the lifespan of most innate ...

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

The epigenetically-encoded memory of the innate immune system

Current Opinion in Immunology, 2020
Stimulation or infection of innate immune cells induces profound epigenetic changes, including the induction of histone modifications and alterations in DNA methylation levels. While some of these changes are rapidly reversible, others appear to be long-lasting, even in mitotic populations, with important functional consequences for the stimulus ...

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Innate Immune Memory: Time for Adopting a Correct Terminology [PDF]

Frontiers in Immunology, 2018
The concept of innate immune memory, i.e., a change in the reactivity in innate immune cells previously exposed to various stimuli, is well known in plants, invertebrates and also in vertebrates (1). Innate immune memory differs from adaptive memory for many aspects, including the lack of gene rearrangements, the involvement of epigenetic reprogramming,

Yeast Gcn2 retains activity following humanization of its auto‐phosphorylation region

FEBS Open Bio, EarlyView.
Using Saccharomyces cerevisiae as a model to study Gcn2 activation and regulation is limited by the lack of antibodies detecting phosphorylated Gcn2. To overcome this, we engineered Gcn2‐HsC, a yeast Gcn2 variant recognizable by commercial anti‐human phospho‐GCN2 antibodies.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

FEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

A dual nature of γδ T cell immune memory responses

eLife
Immune memory was considered for decades an exclusive hallmark of the adaptive immune response. However, recent studies have revealed that innate immune cells can also ‘recall’ information of a primary insult during infection or vaccination and deploy ...
