First description of a histamine receptor of class 2 (HRH2) in a protochordate: expression during blastogenesis and role in regulation of ciliary beat frequency [PDF]

open access: yes, 2016
Histaminergic receptors belong to the family of seven-transmembrane \u3b1-helix domain receptors classified in mammals into four distinct classes. Despite being widely studied in vertebrates, few data are available on the invertebrate receptors, with ...

Creation and maintenance of variation in allorecognition loci

open access: yesFrontiers in Immunology, 2011
Allorecognition is the ability of an organism to differentiate self or close relatives from unrelated individuals. Effective allorecognition systems are critical to the survival of organisms; they prevent inbreeding, protect against pathogens, and ...

Colony Specificity in the Xenogeneic Combinations among Four Botrylloides Species (Urochordata, Ascidiacea) [PDF]

open access: yes, 2002
Xenogeneic rejection reactions were histologically examined among four compound ascidians of the genus Botrylloides; B. simodensis, B. lentus, B. fuscus and B. violaceus, to compare with the allogeneic rejections of these species.

Exogenous IL-8 induces phagocyte activation in the compound ascidian Botryllus schlosseri

open access: yesInvertebrate Survival Journal, 2006
We studied the responses of Botryllus schlosseri phagocyte to human recombinant IL-8 (hrIL-8) at three different concentrations (10, 25 and 50 ng/ml). Both spreading ability and phagocytosis were significantly enhanced by the exogenous chemokine at 25 ...

Investigating diet as the source of tetrodotoxin in Pleurobranchaea maculata [PDF]

open access: yes, 2014
The origin of tetrodotoxin (TTX) is highly debated; researchers have postulated either an endogenous or exogenous source with the host accumulating TTX symbiotically or via food chain transmission.

Histological Differences between the Color Patterns of Two Strains of the Compound Ascidian Polyandrocarpa misakiensis [PDF]

open access: yes, 1993
We examined histological differences between the color patterns of two strains of the compound styelid ascidian Polyandrocarpa misakiensis. Two strains in this species show different color patterns.
