Cell Rep Methods . 2022 May; 2(5):100220. PMID: 35637912
We present a bimodal endocytic tracer, fluorescent BSA-gold (fBSA-Au), as a fiducial marker for 2D and 3D correlative light and electron microscopy (CLEM) applications. fBSA-Au consists of colloidal gold (Au)...

PLoS One . 2020 Nov; 15(11):e0238484. PMID: 33232321
Antigen cross presentation, whereby exogenous antigens are presented by MHC class I molecules to CD8+ T cells, is essential for generating adaptive immunity to pathogens and tumor cells. Following endocytosis,...

J Am Soc Nephrol . 2020 Aug; 31(9):2044-2064. PMID: 32764142
Background: APOL1 is found in human kidney podocytes and endothelia. Variants G1 and G2 of the gene account for the high frequency of nondiabetic CKD among African Americans. Proposed mechanisms...

Elife . 2019 Dec; 8. PMID: 31868166
While the heart regenerates poorly in mammals, efficient heart regeneration occurs in zebrafish. Studies in zebrafish have resulted in a model in which preexisting cardiomyocytes dedifferentiate and reinitiate proliferation to...

Mobius W, Posthuma G
Tissue Cell . 2018 Sep; 57:90-102. PMID: 30201442
Since the pioneering work of Kiyoteru Tokuyasu in the 70ths the use of thawed cryosections prepared according to the "Tokuyasu-method" for immunoelectron microscopy did not lose popularity. We owe this...

Willemen H, Kavelaars A, Prado J, Maas M, Versteeg S, Nellissen L, et al.
PLoS Biol . 2018 Feb; 16(2):e2003452. PMID: 29444090
Chronic pain is a debilitating problem, and insights in the neurobiology of chronic pain are needed for the development of novel pain therapies. A genome-wide association study implicated the 5p15.2...

Sci Rep . 2016 Sep; 6:32948. PMID: 27624595
Host defence peptides (HDPs) have the potential to become alternatives to conventional antibiotics in human and veterinary medicine. The HDP chicken cathelicidin-2 (CATH-2) has immunomodulatory and direct killing activities at...
