Abstract
The transmission electron microscopy revealed a dendritic cell in the medulla of the chicken bursal follicle. This dendritic cell has a classical secretory machinery; therefore, it has been named a bursal secretory dendritic cell (BSDC). The corticomedullary epithelial arch (CMEA) encloses lymphoid-like cells, which can proliferate and after entering the medulla, begin to differentiate to immature, then mature BSDC, which discharges glycoprotein (gp). With the exhaustion of gp production, the BSDC rapidly transforms into a macrophage-like cell (Mal), which is an activated endocytic cell of innate immunity. The Mal drifts through the follicle-associated epithelium (FAE)-supporting cells into the FAE, and via FAE, the Mal is eliminated in the bursal lumen. The infectious bursal disease virus (IBDV) infection accelerates the maturation process of BSDC precursors, which results in acute emptying of CMEA and subsequently, numerous immature BSDC(s) emerge. The IBDV infection stops the gp discharge, and the gp appears in the virus-containing Mal. The Movat pentachrome staining recognizes the gp in the extracellular spaces of the medulla and after infection in the Mal. The BSDC is the primary target of the IBDV. During IBDV infection, a large number of suddenly formed Mal actively migrate into the cortex, initiating cytokine storm and recruiting heterophil granulocytes. During embryogenesis, the vimentin-positive, possibly embryonic dendritic cells provide a microenvironment for carbohydrate switch. Around hatching, these embryonic, temporary dendritic cells get the Fc receptor, which bind maternal IgY. The posthatched forms of BSDC(s) gradually replace the embryonic ones and bind their own IgY.

Abstract
Bursa of Fabricius (BOF) is a unique immune organ of birds. It is the place where lymphocytes develop, differentiate and mature. Young chicken BOF is susceptible to infection and damage, and even atrophy, causing immune suppression, and bringing huge economic losses to chicken production. Therefore, studying the regulatory mechanism of chicken bursa development is of great practical significance for disease prevention and diagnosis. Jinhu silky chicken (JSC) is a local excellent breed in the Fujian Province of China and with strong disease resistance. However, studies on the disease resistance of JSC are scarce. This study aimed to provide a theoretical basis for reproduction and disease control of JSC. Developmental features of the structure and the IL-21-positive cell (IL-21 PC) distribution on the BOF in JSC were measured from 7 to 300 days of age. Bursas of chicken (n = 36) were taken at 7, 35, 70, 150, 240, and 300 days of age for preparation of paraffin sections and stained with hematoxylin-eosin (HE) and immunohistochemistry. The microstructure of JSC's BOF was similar to that of other poultry. The cortical-medullary boundary of the bursa nodule was not obvious at 7 days of age, but it was evident after 35 days of age. Before 70 days of age, IL-21 positive cells (PC) were scattered on the BOF. At 150 days of age, the number of IL-21 PC in the bursa were the highest and the nuclei were clear. The level of IL-21 PC gradually decreased with age. The BOF degenerated and disappeared in 300-day-old JSC. The histological structure of the BOF was similar to that of other poultry. IL-21 PC were widespread in the BOF at different ages, but the numbers were different.

Abstract
The current study aimed to evaluate the efficacy of selenium nanoparticles (SeNPs), combined or loaded with chitosan (COS), in broiler chickens reared under standard management protocols. The parameters under investigation were production performance, organ development, components of the intestinal barrier, and ileal microbial count. Two hundred and forty day-old chicks were raised in five groups, with each group containing eight replicates (n=6/replicate). The control group received a basal diet whereas the other four groups received basal diets supplemented with SeNPs (0.5 mg/kg), COS (200 mg/kg), SeNPs+COS (0.5 mg/kg SeNPs + 200 mg/kg COS), and SeNPs-loaded COS (SeNPs-L-COS) (200 mg/kg) respectively. On day 35, two birds/replicate were sampled to collect the viscera under investigation. The results revealed that dietary inclusion of SeNPs-L-COS increased (p<0.05) the body weight gain and improved (p<0.05) feed conversion ratio. Similarly, SeNPs-L-COS supplementation increased (p<0.05) the small intestinal villus surface area as well as the count of acidic goblet cells and intraepithelial lymphocytes when compared with the control group. Whereas the total goblet cell count was higher (p<0.05) in the small intestines of both the SeNPs+COS and SeNPs-L-COS groups. Microbial analysis of ileal contents also revealed an increase (p<0.05) in Lactobacilli species count with a concurrent decrease (p<0.05) in Escherichia coli count in the SeNPs-L-COS group when compared with the COS and control groups. Based on the results of the current trial, we can conclude that supplementation with SeNPs-L-COS is a superior combination for promoting the gut health and performance of broilers.

Abstract
Aflatoxin B1 (AFB1) causes toxic effect and leads to organ damage in broilers. Marine algal polysaccharides (MAP) of Enteromorpha prolifera exert multiple biological activities, maybe have a potential detoxification effect on AFB1, but the related research in broilers is extremely rare. Therefore, the purpose of this study was to investigate whether MAPs can alleviate AFB1-induced oxidative damage and apoptosis of bursa of Fabricius in broilers. A total of 216 five-week-old male indigenous yellow-feathered broilers (with average initial body weight 397.35 ± 6.32 g) were randomly allocated to one of three treatments (6 replicates with 12 broilers per replicate), and the trial lasted 4 wk. Experimental groups were followed as basal diet (control group); basal diet mixed with 100 μg/kg AFB1 (AFB1 group, the AFB1 is purified form); basal diet with 100 μg/kg AFB1 + 2,500 mg/kg MAPs (AFB1 + MAPs group). The results showed that the diet with AFB1 significantly decreased the relative weight of bursa of Fabricius (P < 0.05), antioxidant enzymes activities of total superoxide dismutase (T-SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione S-transferase (GST), and total antioxidation capacity (T-AOC), while increased malondialdehyde (MDA) content (P < 0.05). Besides, compared with AFB1 group, dietary MAPs improved the relative weight of bursa of Fabricius and activities of antioxidant enzymes (T-SOD, GSH-Px, CAT, GST) with decreased MDA contents (P < 0.05). Moreover, the consumption of AFB1 downregulated the mRNA expression of SOD1, SOD2, GSTA3, CAT1, GPX1, GPx3, GSTT1, Nrf2, HO-1, and p38MAPK (P < 0.05). Dietary MAPs upregulated the mRNA expression of SOD2, GSTA3, CAT1, GPX1, GSTT1, p38MAPK, Nrf2, and HO-1 in comparison with AFB1 group (P < 0.05). The histological analysis confirmed restoration of apoptotic cells of bursa of Fabricius (P < 0.01), which seen with MAPs supplemented broilers. Besides, dietary MAPs down-regulated the mRNA expression of caspase-3 and Bax (P < 0.05), while up-regulated the mRNA expression of Bcl-2 (P < 0.05) compared with AFB1 group. In addition, according to protein expression results, dietary MAPs up-regulated the protein expression level of antioxidant and apoptosis-associated proteins (Nrf2, HO-1, p38MAPK, Bcl-2) (P < 0.01), but down-regulated the protein expression level of caspase-3 and Bax (P < 0.01). In conclusion, dietary MAPs alleviated AFB1-induced bursa of Fabricius injury through regulating Nrf2-mediated redox and mitochondrial apoptotic signaling pathway in broilers.

Abstract
To investigate the effects of sodium selenite against aflatoxin B1 (AFB 1), 200 male Avian broilers, divided into five groups, were fed with basal diet (control group), 0.3 mg/kg AFB1 (AFB1 group), 0.3 mg/kg AFB1 + 0.2 mg/kg Se (+Se group I), 0.3 mg/kg AFB1 + 0.4 mg/kg Se (+Se group II) and 0.3 mg/kg AFB1 + 0.6 mg/kg Se (+Se group III), respectively. Compared with the control group, decreased relative weight of bursa of Fabricius and contents of serum immunoglobulin, more vacuoles and debris in the bursal lymphoid follicle, and increased percentage of apoptotic bursal cells were observed in the AFB1 group. Sodium selenite, however, could increase the relative weight of bursa of Fabricius and contents of serum immunoglobulin, and ameliorate histopathological lesions. The percentages of apoptotic bursal cells, through flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method, in the three +Se groups were lower than those in the AFB 1 group. Compared with the AFB 1 group, moreover, the mRNA expressions of Bax and Caspase-3 by qRT-PCR in the three +Se groups were decreased, while the expression of Bcl-2 was increased. The results indicate that sodium selenite in diet can protect chicken from AFB 1-induced impairment of humoral immune function by reducing bursal histopathological lesions and percentages of apoptotic bursal cells.

Abstract
In many mammals and birds, B cell lymphopoiesis takes place in GALT, such as the avian bursa of Fabricius. Although BCR expression is sufficient for bursal colonization, the role of BCR ligation in the later stages of bursal B cell lymphopoiesis remains elusive. To address this directly, we introduced a surface Ig-related construct with defined Ag specificity containing the Ag-binding portion of a lamprey variable lymphocyte receptor specific for PE fused to a truncated chicken μ-chain (VLR(PE)Tμ) into developing chick embryos. VLR(PE)Tμ expression supports bursal follicle colonization, clonal expansion, and Ig V gene diversification. VLR(PE)Tμ-expressing B cells migrate to the periphery in the absence of the Ag starting from day 18 of embryogenesis. VLR(PE)Tμ-expressing B cells declined rapidly in the bursa and periphery in the absence of Ag after hatch; however, intrabursal injection of PE prolonged survival of VLR(PE)Tμ(+) bursal and peripheral B cells. Intrabursal introduction of Ag increased emigration of short-lived LT2(+) B cells. Peripheral VLR(PE)Tμ(+) B cells were maintained following intrabursal PE application and contained both short-lived LT2(+) and long-lived LT2(-) B cells. In the chicken bursa, the later stages of B cell development occur in the presence of gut-derived Ag; therefore, we conclude that Ag-mediated ligation of BCR in bursal B cells acts to positively select bursal B cells into both short-lived and long-lived peripheral B cell populations.

Abstract
The bursa of Fabricius is a primary lymphoid organ for B-cell development and gut-associated lymphoid tissue. After hatching, IgG-containing cells with reticular branches are found in the medulla of bursal follicles on frozen sections stained with anti-Cγ antibody, and IgM(+)IgG(+) B cells are detected in single-cell suspension of the bursa. IgG-containing cells in the medulla do not biosynthesize IgG and are composed of aggregated maternal IgG and environmental antigens. Then, those cells in the medulla are acknowledged as follicular dendritic cells retaining immune complexes. Also, it is presumed that IgM(+)IgG(+) B cells are generated by the attachment of immune complexes to IgM(+) bursal B cells because IgM(+)IgG(+) B cells are induced by antigen-dependent attachment of maternal IgG. Therefore, it is reasonable to suppose that immune complexes exert further B-cell differentiation in the medulla.

Abstract
Humoral immune responses in birds, contrary to mammals, depend on the normal functioning of bursa Fabricii. Recent studies have delivered new information about the structure, development and origin of cells that compose the bursa environment. Several viral infections affect bursa, causing lymphocyte depletion or excessive proliferation. This review summarizes data on the development and histology of healthy bursa and introduces some common disorders that affect this organ.
