GrandQC: A comprehensive solution to quality control problem in digital pathology.

Histological slides contain numerous artifacts that can significantly deteriorate the performance of image analysis algorithms. Here we develop the GrandQC tool for tissue and multi-class artifact segmentation. GrandQC allows for high-precision tissue segmentation (Dice score 0.

Blood immune profiling of Ethiopian patients with breast cancer highlights different forms of immune escape.

Breast cancer (BC) is a leading cause of death worldwide, particularly also among African woman. In order to better stratify patients for the most effective (immuno-) therapy, an in depth characterization of the immune status of BC patients is required. In this study, a cohort of 65 Ethiopian patients with primary BC underwent immune profiling by multicolor flow cytometry on peripheral blood samples collected prior to surgery and to any other therapy.

Immune landscape of the tumour microenvironment in Ethiopian breast cancer patients.

Background: The clinical management of breast cancer (BC) is mainly based on the assessment of receptor expression by tumour cells. However, there is still an unmet need for novel biomarkers important for prognosis and therapy. The tumour immune microenvironment (TIME) is thought to play a key role in prognosis and therapy selection, therefore this study aimed to describe the TIME in Ethiopian BC patients.

JNK1 inhibitors target distal B cell receptor signaling and overcome BTK-inhibitor resistance in CLL.

Inhibition of the proximal B cell receptor (BCR) signaling pathway by BTK inhibitors is highly effective in the treatment of CLL, but drug resistance or intolerance occurs. Here, we investigated c-Jun N-terminal protein kinase 1 (JNK1) as an alternative drug target in the distal BCR pathway. JNK1 was preferentially overexpressed and activated in poor prognostic CLL with unmutated IGHV.
