    This collection, curated by Ho-Keung Ng of the Chinese University of Hong Kong, focuses on the underlying pathogenetic and molecular processes that contribute to brain tumors. Papers include a review on grading of adult diffuse gliomas according to the 2021 WHO Classification of Tumors of the Central Nervous System, a description of circulating tumor DNA profiling for childhood brain tumors, and a study on the plasticity of glioma stem cells in response to changes in the microenvironment.

    Biology has evolved greatly in the past decade as high-throughput technologies were developed and applied to various biological disciplines. These technologies have generated an unprecedented amount and new types of biological data and how to make sense of “big data” is an emerging technological and conceptual challenge. Computational biology largely relies on computational and statistical algorithms to better understand biological processes. The editors of LI commissioned experts in the fields of computational biology and pathology to compile a special issue on computational pathology. We include original research, technical reports and review articles that use, modify, improve, develop, or summarize computational algorithms to solve biomedical questions.

    The 2021 Nobel Prize in Physiology or Medicine was awarded to David Julius and Ardem Patapoutian “for their discoveries of receptors for temperature and touch”. In recognition of their work, the LI editors present an updated collection of papers that explore the mechanisms of transient receptor potential ion channels. Transient receptor potential (TRP) ion channels serve as cellular sensors that respond to a range of physical and chemical stimuli. Twenty-eight mammalian TRP ion channels have been reported, which belong to six subfamilies (TRPV, TRPM, TRPC, TRPA, TRPP, and TRPML). This collection of articles from Laboratory Investigation describes the roles of various TRP ion channels in inflammation, fibrosis and cancer.

    Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease worldwide. The pathological spectrum of NAFLD ranges from simple steatosis to the necro-inflammatory and fibro-progressive form, non-alcoholic steatohepatitis (NASH), which may then progress to cirrhosis, liver failure and hepatocellular carcinoma. This web focus features papers from Laboratory Investigation and Modern Pathology that present new models and techniques, diagnostic advances, mechanistic insights and potential innovative therapies for NAFLD and NASH.
