Polyfunctional CD8+CD226+RUNX2hi effector T cells are diminished in advanced stages of chronic lymphocytic leukemia

Molecular Oncology, EarlyView.
CD226+CD8+ T cells express elevated levels of RUNX2, exhibit higher proliferation capacity, cytokines and cytolytic molecules expression, and migratory capacity. In contrast, CD226−CD8+ T cells display an exhausted phenotype associated with the increased expression of co‐inhibitory receptors and impaired effector functions.

Caspase-independent type III programmed cell death in chronic lymphocytic leukemia: the key role of the F-actin cytoskeleton

Haematologica, 2009
Background Programmed cell death has been traditionally related with caspase activation. However, it is now accepted that caspase-independent forms of programmed cell death also regulate cell death.

Deep generative selection models of T and B cell receptor repertoires with soNNia [PDF]

, 2020
Subclasses of lymphocytes carry different functional roles to work together to produce an immune response and lasting immunity. Additionally to these functional roles, T and B-cell lymphocytes rely on the diversity of their receptor chains to recognize different pathogens.

Chronic Lymphocytic Leukemia — Microenvironment and B Cells

, 2015
Chronic lymphocytic leukemia (CLL) has been considered as an accumulative disease deriving from defects in apoptosis, but recent studies showed that CLL is a dynamic process in which monoclonal B cells proliferate within pseudofollicular proliferation centers.

Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

Molecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

Surface-antigen expression profiling of B cell chronic lymphocytic leukemia: from the signature of specific disease subsets to the identification of markers with prognostic relevance

Journal of Translational Medicine, 2006
Studies of gene expression profiling have been successfully used for the identification of molecules to be employed as potential prognosticators.

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential

Molecular Oncology, EarlyView.
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

Autosomal recessive hyper‐IgE syndrome due to DOCK8 deficiency: An adjunctive role for omalizumab

Journal of Cutaneous Immunology and Allergy, Volume 5, Issue 6, Page 222-226, December 2022., 2022
We report a rare case of AR‐HIES with DOCK8 deficiency in a young male that was successfully treated by infection management, skincare, diet elimination, and omalizumab. Abstract Autosomal recessive hyper‐IgE syndrome (AR‐HIES) is a rare primary immunodeficiency disorder characterized by high serum IgE levels, recurrent viral skin infections, severe ...

Multicenter study of ZAP-70 expression in patients with B-cell chronic lymphocytic leukemia using an optimized flow cytometry method

Haematologica, 2008
Background Flow cytometry allows specific assessment of the expression of ZAP-70, a promising new prognostic factor in B-cell chronic lymphocytic leukemia (B-CLL), but suffers from a lack of multicenter standardization.Design and Methods An optimized ...

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible
