IL-4 Background
Interleukin-4 (IL-4) induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. Upon activation by IL-4, Th2 cells subsequently produce additional IL-4. IL-4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. It is a key regulator in humoral and adaptive immunity. IL-4 induces B-cell class switching to IgE, and up-regulates MHC class II production. Overproduction of IL-4 is associated with allergies.

Abstract
Infectious bronchitis virus (IBV) is a highly contagious avian coronavirus. IBV causes substantial worldwide economic losses in the poultry industry. Vaccination with live-attenuated viral vaccines, therefore, are of critical importance. Live-attenuated viral vaccines, however, exhibit the potential for reversion to virulence and recombination with virulent field strains. Therefore, alternatives such as subunit vaccines are needed together with the identification of suitable adjuvants, as subunit vaccines are less immunogenic than live-attenuated vaccines. Several glycan-based adjuvants directly targeting mammalian C-type lectin receptors were assessed in vitro using chicken bone marrow-derived dendritic cells (BM-DCs). The β-1-6-glucan, pustulan, induced an up-regulation of MHC class II (MHCII) cell surface expression, potentiated a strong proinflammatory cytokine response, and increased endocytosis in a cation-dependent manner. Ex vivo co-culture of peripheral blood monocytes from IBV-immunised chickens, and BM-DCs pulsed with pustulan-adjuvanted recombinant IBV N protein (rN), induced a strong recall response. Pustulan-adjuvanted rN induced a significantly higher CD4+ blast percentage compared to either rN, pustulan or media. However, the CD8+ and TCRγδ+ blast percentage were significantly lower with pustulan-adjuvanted rN compared to pustulan or media. Thus, pustulan enhanced the efficacy of MHCII antigen presentation, but apparently not the cross-presentation on MHCI. In conclusion, we found an immunopotentiating effect of pustulan in vitro using chicken BM-DCs. Thus, future in vivo studies might show pustulan as a promising glycan-based adjuvant for use in the poultry industry to contain the spread of coronaviridiae as well as of other avian viral pathogens.

Avian Pathol. 2016;45(2):235-43. doi: 10.1080/03079457.2016.1144919.
Applications: Stimulation of chicken bone marrow-derived dendritic cells (chBM-DCs) with chicken GM-CSF and IL-4 in culture.
Abstract
Salmonella enterica serovar Gallinarum (SG) is a Gram-negative intracellular host-adapted pathogen that causes fowl typhoid. Attenuated strains of SG are proven and widely used vaccine candidates because of advantages like induction of strong humoral and cell-mediated immune responses. In the present study, we investigated the interaction of chicken bone marrow-derived dendritic cells (chBM-DCs) with an attenuated SG (JOL1355) strain that secretes a heat-labile enterotoxin B subunit protein previously shown to successfully vaccinate chickens. ChBM-DCs were isolated and cultured in the presence of recombinant chicken GM-CSF and IL-4 cytokines. The chBM-DCs were infected with JOL1355 at an multiplicity of infection of 10. JOL1355 was able to invade dendritic cells (DCs); however, the survival of JOL1355 in DCs decreased over time. At 24 h post infection, IL-6, IL-10 and IFN-γ transcript levels were significantly increased in JOL1355-infected DCs compared to non-stimulated DCs. Flow cytometry analysis showed an increased proportion of cells producing CD40, CD80, and MHC class II in the JOL1355-infected cultures compared to the non-stimulated control. In addition, JOL1355-stimulated chBM-DCs could induce significant expression of IL-2 in co-culture with autologous CD4+ T cells. Based on these results, we conclude that chBM-DCs are capable of internalizing the live attenuated SG vaccine candidate and the infected chBM-DCs show signs of maturation as evidenced by the upregulated expression of costimulatory molecules and cytokines.
