Synergy between TMZ and individualized multimodal immunotherapy to improve overall survival of IDH1 wild-type MGMT promoter-unmethylated GBM patients.

The prognosis of IDH1 wild-type MGMT promoter-unmethylated GBM patients remains poor. Addition of Temozolomide (TMZ) to first-line local treatment shifted the median overall survival (OS) from 11.8 to 12.

Flow cytometric measurement of STAT5 phosphorylation in cytomegalovirus-stimulated T cells.

Cytomegalovirus (CMV)-specific T cells expand with CMV reactivation and are probably prerequisite for control and protection. Given the critical role STAT5A phosphorylation (pSTAT5A) in T cell proliferation, this study presents a simple and sensitive flow cytometric-based pSTAT5A assay to quickly identify CMV-specific T cell proliferation. We determined pSTAT5A in T cells treated with CMV-specific peptide mix (pp65 + IE1 peptides) from 20 healthy adult subjects and three immunodeficient patients with CARMIL-2 mutation.

Evaluating STAT5 Phosphorylation as a Mean to Assess T Cell Proliferation.

Here we present a simple and sensitive flow cytometric-based assay to assess T cell proliferation. Given the critical role STAT5A phosphorylation in T cell proliferation, we decided to evaluate phosphorylation of STAT5A as an indicator of T cell proliferation. We determined pSTAT5A in T cell treated with either CD3/CD28 or PHA.

Molecular mechanism of LPS-induced TNF-α biosynthesis in polarized human macrophages.

In response to environmental stimuli such as granulocyte-macrophage or macrophage colony stimulating factor (GM-CSF/M-CSF), macrophages (MΦ) can acquire distinct functional phenotypes that control inflammatory processes on the one hand and contribute to a broad spectrum of pathologies on the other. Potential intervention strategies will require an understanding of the signalling processes that are associated with macrophage polarization. In the present study, we show that M-MΦ produce more IFN-β and IL-10 and a lot less TNF-α than do GM-MΦ in response to LPS.

Flow Cytometric Evaluation of Primary Immunodeficiencies.

Primary immunodeficiency diseases are genetic disorders that mostly cause susceptibility to infections and are sometimes associated with autoimmune and malignant diseases. For early detection and management of these diseases, flow cytometric procedures allow an encompassing assessment of cellular phenotypes and cellular functions. State-of-the art cytometry is based today on 8- to 10-color staining and includes an assessment of lineage maturation and functional markers.
