Physiological and biochemical aspects of the avian uropygial gland
(Instituto Internacional de Ecologia, 2009)
This review discusses different aspects of the uropygial gland of birds. The gland exhibits a striking morphological
diversity in size, shape and presence/absence of tufts of feathers. It was shown that acidic mucins, ...
Cleavage of Peptides from Amphibian Skin Revealed by Combining Analysis of Gland Secretion and in Situ MALDI Imaging Mass Spectrometry
(American Chemical Society, 2018-05)
Peptides from skin secretions of amphibians are considered important components of their immune system and also play a relevant role in their defense mechanism against predators. Herein, by using mass spectrometry (MS), ...
Effect of TGF-b1 stimulation on the secretome of human adipose-derived mesenchymal stromal cells
(Wiley, 2015-08)
Adipose tissue is an attractive source of mesenchymal stromal cells (MSCs) owing to the relative ease of obtaining large volumes with more MSC abundance compared with other sources. Increasing evidence supports the fact ...
BR-bombesin: a novel bombesin-related peptide from the skin secretion of the Chaco tree frog (Boana raniceps) with physiological gastric effects
(Springer, 2022-03-13)
Bombesin mediates several biological activities in the gastrointestinal (GI) tract and central nervous system in mammals, including smooth muscle contraction, secretion of GI hormones and regulation of homeostatic mechanisms. ...
Effect of translocator protein (18 kDa)-ligand binding on neurotransmitter-induced salivary secretion in rat submandibular glands
(Portland Press, 2008-07)
Background information. TSPO (translocator protein), previously known as PBR (peripheral-type benzodiazepine receptor), is a ubiquitous 18 kDa transmembrane protein that participates in diverse cell functions. High-affinity ...
Type VI secretion system in pathogenic escherichia coli: structure, role in virulence, and acquisition
(Frontiers Media, 2019-08)
Bacterial pathogens utilize a myriad of mechanisms to invade mammalian hosts, damage tissue sites, and evade the immune system. One essential strategy of Gram-negative bacteria is the secretion of virulence factors through ...
SLAM and CD31: signaling molecules involved in cytokine secretion during the development of innate and adaptive immune responses
(Elsevier, 2007-02)
Immune cells are modulated through the crosslinking of receptors named “immunoreceptors”. Ligation of immunoreceptors by their ligands induces a tyrosine-phosphorylation signal that is essential for cell activation or ...
Oomycete intracellular effectors: Specialized weapons targeting strategic plant processes
(Wiley Blackwell Publishing, Inc, 2021-10-27)
Oomycete phytopathogens have adapted to colonise plants using effectors as their molecular weapons. Intracellular effectors, mostly proteins but also small ribonucleic acids, are delivered by the pathogens into the host ...
