“…The heterophile count in the T1 and T2 groups exhibited a significant difference compared to the control group (p<0.05); only the heterophils in the T3 (inorganic Se) group did not exhibit a significant difference compared to the control (p>0.05). It is assumed that SY contains glucan from the Saccharomyces cerevisiae cell wall as an active component that plays a crucial role in the non-specific stimulation of immune response [22]. Therefore, using organic selenium, a combination of selenium and yeast may affect the immune response.…”

Background and Aim: The presence of free radicals may lower chicken's performance. Thus, the antioxidant defense is needed and can be made through a nutritional approach such as selenium supplementation before hatches. This study aimed to investigate the type of selenium that, as an in ovo feeding (IOF) material, can provide the most enhancement of immunity, villi surface area, and early growth performance of local chickens. Materials and Methods: This study, with a completely randomized design, used 480 fertile Kampung Unggul Balitbangtan (KUB, a selected local breed) chicken eggs, with 120 eggs per treatment for four treatments. The four treatments of IOF material included the treatment with organic selenium yeast (SY), organic hydroxy-selenomethionine (HSM), inorganic sodium selenite (SS), and uninjected selenium (control). A solution containing 0.15 ppm of different selenium was injected into the egg amnion after 18 days of incubation. Once hatched, the chicks were placed in three individual cages for each treatment (capacity of eight birds per cage). The parameters observed were the villi surface area, antibody titer, the number of total and differentiated leucocytes, glutathione peroxidase (GSH-Px) activity levels, and growth and feed efficiency of the early growth performance. Results: All the in ovo selenium feeding, except SS, significantly affected the villi surface area, antibody titer, and lymphocyte and heterophil percentages; however, the feedings were still not optimal for enhancing antibody titers and total and differentiated leukocytes. All types of selenium were demonstrated to increase the activity of GSH-Px significantly compared to the control treatment (p<0.05). Furthermore, the daily gain and feed conversion ratio of the groups treated with SY and HSM was significantly improved compared to that of the control group. Conclusion: In ovo SY and HSM improve immunity significantly, villi surface areas and performance. Therefore, both types are the best nutrient ingredients of IOF for building immunity and producing good performance in chickens.

“…Pathogen-associated molecular patterns (PAMPs)bacterial peptidoglycans (lipopolysaccharides, lipoteichoic acids), fungal and algal βglucans, and viral nucleic acidsare intercepted by pathogen recognition proteins (PRPs) dissolved within the lymph and/or spanning the membranes of haemocytes (Cerenius and Söderhäll, 2018). Peptidoglycan-binding proteins (Wei et al, 2012b;Vaseeharan, 2012), C-type lectins (Wang et al, 2011;Wei et al, 2012a), β-glucan binding proteins (Cerenius et al, 1994;Zhao et al, 2009;Itoh et al, 2010), serineprotease homologues (Sriphaijit et al, 2007;Zhang et al, 2009), members of the immunoglobulin superfamily (Dscam, FREPs) amongst many other PRPs and their transcriptional variants have been functionally characterised in shellfish (Cooper and Alder, 2006;Ghosh et al, 2011). Signal transduction cascades, arising from the activation of cellular receptors, trigger the translocation of transcription factors into the nucleus to switch-on the expression of immune-associated mRNAs.…”

“…The protein families can be further grouped by potential functions. The hemocytin/mucin [66], apolipophorin [67], vitellogenin [68], SVWC (single domain von Willebrand factor type C) [69], putative defense protein [70], C-type lectin [71] and CAP (cysteine-rich secretory proteins, antigen 5 and pathogenesis-related 1 proteins) families are all implicated in arthropod innate immunity by the promotion of pathogen agglutination, although each protein could also perform other biological functions, including lipid transport involved with reproduction. The fasciclin [72] family has a potential broad adhesion function, while the remaining families likely function with a more specialized binding capacity (proteoglycans: glycoprotein with carbohydrate and calcium binding; annexin: phospholipid binding [73]; acetylcholine receptor: acetylcholine binding; cuticle proteins: chitin binding).…”

“…Arthropods possess an innate immune system that functions by finding and destroying pathogens through a variety of means, including lysis, agglutination, melanization and phagocytosis [ 77 ]. The phenoloxidase cascade can be activated by multiple prophenoloxidase activating factors, including serine proteases [ 78 ] and apolipophorins [ 67 ]. Hemocytin [ 66 ], vitellogenin [ 68 ], apolipophorin [ 79 ], single domain von Willebrand factor type C [ 69 ] and C-type lectin [ 71 ] proteins bind to carbohydrates found on pathogen cells to initiate agglutination.…”

Comparative analysis of stalked and acorn barnacle adhesive proteomes

Barnacles interest the scientific community for multiple reasons: their unique evolutionary trajectory, vast diversity and economic impact—as a harvested food source and also as one of the most prolific macroscopic hard biofouling organisms. A common, yet novel, trait among barnacles is adhesion, which has enabled a sessile adult existence and global colonization of the oceans. Barnacle adhesive is primarily composed of proteins, but knowledge of how the adhesive proteome varies across the tree of life is unknown due to a lack of genomic information. Here, we supplement previous mass spectrometry analyses of barnacle adhesive with recently sequenced genomes to compare the adhesive proteomes of Pollicipes pollicipes (Pedunculata) and Amphibalanus amphitrite (Sessilia). Although both species contain the same broad protein categories, we detail differences that exist between these species. The barnacle-unique cement proteins show the greatest difference between species, although these differences are diminished when amino acid composition and glycosylation potential are considered. By performing an in-depth comparison of the adhesive proteomes of these distantly related barnacle species, we show their similarities and provide a roadmap for future studies examining sequence-specific differences to identify the proteins responsible for functional differences across the barnacle tree of life.
