Engagement of TL3, TLR7 and NKG2D regulates IFN-gamma secretion but not NKG2D-mediated cytotoxicity by human NK cells stimulated with suboptimal doses of IL-12
(American Association of Immunologists, 2007-09)
NK cells express different TLRs, such as TLR3, TLR7, and TLR9, but little is known about their role in NK cell stimulation. In this study, we used specific agonists (poly(I:C), loxoribine, and synthetic oligonucleotides ...
Role of VAMP7-Dependent Secretion of Reticulon 3 in Neurite Growth
(Elsevier, 2020-12)
VAMP7 is involved in autophagy and in exocytosis-mediated neurite growth, two yet unconnected cellular pathways. Here, we find that nutrient restriction and activation of autophagy stimulate axonal growth, while autophagy ...
The Azospirillum brasilense Type VI secretion system promotes cell aggregation, biocontrol protection against phytopathogens and attachment to the microalgae Chlorella sorokiniana
(Wiley Blackwell Publishing, Inc, 2021-09)
The plant-growth-promoting bacterium Azospirillum brasilense is able to associate with the microalgae Chlorella sorokiniana. Attachment of A. brasilense increases the metabolic performances of the microalgae. Recent genome ...
Evidence for constitutive bone morphogenetic protein-2 secretion by M1 macrophages: Constitutive auto/paracrine osteogenic signaling by BMP-2 in M1 macrophages
(Academic Press Inc Elsevier Science, 2017-09)
Mechanisms mediating vascular calcification recapitulate osteogenic processes encompassing bone formation and imply participation of bone related proteins such as bone morphogenetic protein-2 (BMP-2). Macrophages are amongst ...
A vaccine using Anaplasma marginale subdominant type IV secretion system recombinant proteins was not protective against a virulent challenge
(Public Library of Science, 2020-02)
Anaplasma marginale is the most prevalent tick-borne livestock pathogen with worldwide distribution. Bovine anaplasmosis is a significant threat to cattle industry. Anaplasmosis outbreaks in endemic areas are prevented via ...
Effects of chronic Staphylococcus aureus infection on immunological parameters and functionality of macrophages isolated from bovine mammary secretions
(Elsevier, 2019-09)
The aim of this study was to characterize the effects of chronic S. aureus intramammary infection (IMI) on local innate and adaptive immune response during active involution. Cows in late lactation that were either uninfected ...
Laccaria bicolor MiSSP8 is a small-secreted protein decisive for the establishment of the ectomycorrhizal symbiosis
(Wiley Blackwell Publishing, Inc, 2019-10)
The ectomycorrhizal symbiosis is a predominant tree–microbe interaction in forest ecosystems sustaining tree growth and health. Its establishment and functioning implies a long‐term and intimate relationship between the ...
Orexin A and B in vitro modify orexins receptors expression and Gonadotropins secretion of anterior pituitary cells of proestrous rats
(Elsevier Science, 2014-01)
Orexin A and orexin B (hypocretins) are neuropeptidessynthesized mainly by neurons located in the lateral hypothalamus andprojections throughout the brain. They are agonists at both the orexin 1and orexin 2 G protein-coupled ...
Beauty under the mud: Soil crypsis in new species of the Malagasy genus Ankaratrix (Opiliones: Triaenonychidae: Triaenobuninae)
(Elsevier Gmbh, 2020-07)
Camouflaging with crypsis is a known strategy in several invertebrates such as sea urchins, gastropods, crabs, and immature stage of insects. In harvestmen, soil crypsis are used as a defense strategy. The soil particles ...
Diversity and evolution of the parotoid macrogland in true toads (Anura: Bufonidae)
(Wiley Blackwell Publishing, Inc, 2019-09)
Skin glands in amphibians are either distributed throughout the skin or aggregated in multiglandular structures such as the parotoids typical of most species of Bufonidae. Although many early divergent and derived bufonids ...
