SCoPE this out! Improved single-cell proteomics method exposes macrophage proteome heterogeneity.

SCoPE this out! Improved single-cell proteomics method exposes macrophage proteome heterogeneity.

The concept of tissues as heterogeneous populations of cell types with diverse phenotypes is now well recognised thanks to single-cell transcriptomics. Although individual cell specialisation often arises from protein-mediated physiology, …

The FAScinating truth: Innate immune signalling driven by caspase-8 cleavage of N4BP1.

The FAScinating truth: Innate immune signalling driven by caspase-8 cleavage of N4BP1.

Mutations in FAS play a crucial role in the development of severe immunodeficiency, which is promoted by aberrant T lymphocyte death. In addition to this, mutations in caspase-8 or FADD, …

Getting their ducks in a row – LONP1 co-chaperones with mtHSP70 in mitochondrial protein folding.

Getting their ducks in a row – LONP1 co-chaperones with mtHSP70 in mitochondrial protein folding.

Apart from 13 core subunits of the OXPHOS pathway, all the human mitochondrial proteome is encoded by the nuclear genome. Following synthesis on cytosolic ribosomes, proteins for mitochondrial function are …

Ubiquitin ligase marks neo-substrates for degradation with unique Ub code.

Ubiquitin ligase marks neo-substrates for degradation with unique Ub code.

Targeted protein degradation has recently been studied as a possible therapeutic paradigm. Kaiho-Soma et al. were able to establish that the ubiquitin ligase thyroid hormone receptor-interacting protein 12 (TRIP12) accelerates …

The secret interface of the neuroimmune system: the key to immune surveillance.

The secret interface of the neuroimmune system: the key to immune surveillance.

Neuroimmune interactions play a significant role in several neurological disorders and the current state-of-art suggests that central nervous system (CNS)-derived antigens are sorted and presented to circulating T cells. However, …

Recombinant lectins as novel and efficient glycoproteomic tools.

Recombinant lectins as novel and efficient glycoproteomic tools.

Post-translational modifications (PTMs) are crucial biological processes implicated in multiple physiological and pathological pathways. Glycosylation is one such PTM that results in the attachment of glycans, which are chain-like structures …

Getting to the heart of the matter: Comprehensive peptide & oxidation profiling in failing human hearts with UHPLC-MS.

Getting to the heart of the matter: Comprehensive peptide & oxidation profiling in failing human hearts with UHPLC-MS.

Diabetes, obesity, heart disease and ageing have all been strongly associated with oxidative stress. For heart disease in particular, the resultant oxidative protein damage caused has been directly linked to …

A new sensitive and accurate method enables endogenous phosphotyrosine mapping.

A new sensitive and accurate method enables endogenous phosphotyrosine mapping.

Phosphotyrosine (pTyr) plays a central role in many cell-to-cell communication pathways, including those that regulate proliferation, differentiation, adhesion, hormone responses, and immune defense. These pathways are commonly dysregulated in cancer …
