Sign Up to like & getrecommendations! Published in 2019 at "Advances in experimental medicine and biology"
DOI: 10.1007/978-981-13-3588-4_1
Abstract: Antimicrobial peptides of multicellular organisms were first characterized in the 1980s by investigators who felt that known systems of immunity could not explain what they observed: the resistance to bacterial infection of a Cecropia moth… read more here.

DOI: 10.1038/s41467-017-02710-x
Abstract: Noisy gene expression is of fundamental importance to single cells, and is therefore widely studied in single-celled organisms. Extending these studies to multicellular organisms is challenging since their cells are generally not isolated, but individuals… read more here.

DOI: 10.1039/c7mb00462a
Abstract: Altered metabolism is often identified as a cause or an effect of physiology and pathogenesis. But it is difficult to predict the metabolic flux distributions of multicellular organisms due to the lack of an explicit… read more here.

DOI: 10.1073/pnas.1618854114
Abstract: Significance We lay out the first general model of the interplay between intercellular competition, aging, and cancer. Our model shows that aging is a fundamental feature of multicellular life. Current understanding of the evolution of… read more here.

DOI: 10.1103/physrevlett.128.218101
Abstract: Resolution of the intrinsic conflict between the reproduction of single cells and the homeostasis of a multicellular organism is central to animal biology and has direct impact on aging and cancer. Intercellular competition is indispensable… read more here.

DOI: 10.1130/g38680.1
Abstract: Multicellularity arose multiple times in the evolutionary history of eukaryotes, and simple multicellularity may have a deep history tracing back to the Paleoproterozoic. However, complex multicellular organisms with cellular and tissue differentiation did not appear… read more here.

DOI: 10.1146/annurev-genet-022422-095608
Abstract: Autophagy, a lysosome-mediated degradation process evolutionarily conserved from yeast to mammals, is essential for maintaining cellular homeostasis and combating diverse cellular stresses. Autophagy involves de novo synthesis of a double-membrane autophagosome, sequestration of selected cellular… read more here.

DOI: 10.3389/fcell.2020.00409
Abstract: MicroRNAs (miRNAs) are short, regulatory RNAs that act as post-transcriptional repressors of gene expression in diverse biological contexts. The emergence of small RNA-mediated gene silencing preceded the onset of multicellularity and was followed by a… read more here.

DOI: 10.3390/md20090549
Abstract: The innate immune system provides an adequate response to stress factors and pathogens through pattern recognition receptors (PRRs), located on the surface of cell membranes and in the cytoplasm. Generally, the structures of PRRs are… read more here.
