Characterization of fungal carbonyl sulfide hydrolase belonging to clade D β‐carbonic anhydrase

FEBS Letters, EarlyView.
Here, we performed a functional analysis of the fungal enzymes belonging to clade D of the β‐class carbonic anhydrase family (β‐D‐CA). The β‐D‐CAs in the basidiomycete Gloeophyllum trabeum and the ascomycete Trichoderma harzianum showed very low activity in the hydration of CO2 but exhibited high activity in the hydrolysis of carbonyl sulfide (COS ...

EpCAM promotes endosomal modulation of the cortical RhoA zone for epithelial organization

Nature Communications, 2021
The organization and force-generating property of actomyosin dictate the plasticity and behaviour of cells but the spatio-temporal regulation of this network is unclear.

Limiting energy dissipation induces glassy kinetics in single cell high precision responses [PDF]

, 2015
Single cells often generate precise responses by involving dissipative out-of-thermodynamic equilibrium processes in signaling networks. The available free energy to fuel these processes could become limited depending on the metabolic state of an individual cell.

A new homeostatic model of the T cell system [PDF]

Journal of Biological Systems, 19, 299-317, 2011, 2010
Our main tenet argues that the primary role of positive thymic selection and the resulting T cell population is the maintenance of a homeostatic equilibrium with self MHC-self peptide complexes. The homeostatic T cell repertoire can recognize infections non-specifically and this is an indirect (negative) recognition: the whole homeostatic T cell ...

Clonal kinetics and single-cell transcriptional profiling of CAR-T cells in patients undergoing CD19 CAR-T immunotherapy [PDF]

, 2020
Chimeric antigen receptor (CAR) T-cell therapy has produced remarkable anti-tumor responses in patients with B-cell malignancies. However, clonal kinetics and transcriptional programs that regulate the fate of CAR-T cells after infusion remain poorly ...

A histidine‐rich extension of the mitochondrial F0 subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria

FEBS Letters, EarlyView.
The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

MicroRNAs affecting the susceptibility of melanoma cells to CD8+ T cell‐mediated cytolysis

Clinical and Translational Medicine, 2023
Background The regulatory functions of microRNAs (miRNAs) in anti‐tumour immunity have been mainly described in immune effector cells. Since little is known about miRNA effects on the susceptibility of target cells during T cell—target cell interaction ...

T cell equation as a conceptual model of T cell responses for maximizing the efficacy of cancer immunotherapy [PDF]

SOJ Immunol 5(1):1-5, 2017, 2015
Following antigen stimulation, the net outcomes of a T cell response are shaped by integrated signals from both positive co-stimulatory and negative regulatory molecules. Recently, the blockade of negative regulatory molecules (i.e. immune checkpoint signals) demonstrates therapeutic effects in treatment of human cancer, but only in a fraction of ...

Elucidation of interface interactions between a dehydratase domain and an acyl carrier protein in cremimycin polyketide synthase

FEBS Letters, EarlyView.
In modular polyketide synthases, the dehydratase (DH) domain catalyzes the dehydration reaction of the β‐hydroxyacyl unit attached to the cognate acyl carrier protein (ACP) domain. However, it is unclear how DH interacts with ACP during the reaction. In this study, we identified DH–ACP interface residues, providing the first detailed insights into DH ...

A mathematical model to study the impact of intra-tumour heterogeneity on anti-tumour CD8+ T cell immune response [PDF]

arXiv, 2021
Intra-tumour heterogeneity (ITH) has a strong impact on the efficacy of the immune response against solid tumours. The number of sub-populations of cancer cells expressing different antigens and the percentage of immunogenic cells (i.e. tumour cells that are effectively targeted by immune cells) in a tumour are both expressions of ITH. Here, we present
