Ocular light exposure has important influences on human health and well-being through modulation of circadian rhythms and sleep, as well as neuroendocrine and cognitive functions. Prevailing patterns of light exposure do not optimally engage these actions for many individuals, but advances in our understanding of the underpinning mechanisms and emerging lighting technologies now present opportunities to adjust lighting to promote optimal physical and mental health and performance. A newly developed, international standard provides a SI-compliant way of quantifying the influence of light on the intrinsically photosensitive, melanopsin-expressing, retinal neurons that mediate these effects.

Tissue Clearing Approaches in Atherosclerosis.

Methods Mol Biol

March 2022

Institute for Cardiovascular Prevention (IPEK), Klinikum der Universität München, Ludwig-Maximilians-University (LMU), Munich, Germany.

Recent advances in cardiovascular research have led to a more comprehensive understanding of molecular mechanisms of atherosclerosis. It has become apparent that the disease involves three layers of the arterial wall: the intima, the media, and a connective tissue coat termed the adventitia. It is also now appreciated that arteries are surrounded by adipose and neuronal tissues.

Combined Single-Cell RNA and Single-Cell α/β T Cell Receptor Sequencing of the Arterial Wall in Atherosclerosis.

Methods Mol Biol

March 2022

Institute for Cardiovascular Prevention (IPEK), University Hospital of Munich (KUM), Ludwig-Maximilians-University (LMU), Munich, Germany.

Although various pro- and anti-inflammatory T cell subsets have been observed in murine and human atherosclerosis, principal issues of T cell immunity remain unanswered: Is atherosclerosis progression critically affected by aberrant T cell responses? Are tolerance checkpoints compromised during atherosclerosis progression? Answers to these questions will determine if we are at the cusp of developing T cell-dependent therapeutic strategies. Rapid advances in single cell RNA sequencing (scRNA-seq) and single cell α/β T cell receptor (TCR) (scTCR) sequencing allows to address these issues in unprecedented ways. The majority of T cells recognize peptide antigen-MHC complexes presented by antigen-presenting cells which, in turn, trigger activation and proliferation (clonal expansion) of cognate TCR-carrying T cells.

A major goal of methodologies related to large scale gene expression analyses is to initiate comprehensive information on transcript signatures in single cells within the tissue's anatomy. Until now, this could be achieved in a stepwise experimental approach: (1) identify the majority of transcripts in a single cell (single cell transcriptome); (2) provide information on transcripts on multiple cell subtypes in a complex sample (cell heterogeneity); and (3) give information on each cell's spatial location within the tissue (zonation transcriptomics). Such genetic information will allow construction of functionally relevant gene expression maps of single cells of a given anatomically defined tissue compartment and thus pave the way for subsequent analyses, including their epigenetic modifications.

Pantothenate kinase-associated neurodegeneration (PKAN) is a progressive neurodegenerative disease caused by mutations in the pantothenate kinase 2 (PANK2) gene and associated with iron deposition in basal ganglia. Pantothenate kinase isoforms catalyze the first step in coenzyme A (CoA) biosynthesis. Since PANK2 is the only isoform in erythrocytes, these cells are an excellent ex vivo model to study the effect of PANK2 point mutations on expression/stability and activity of the protein as well as on the downstream molecular consequences.
