Subsequent quantification of cytokine profiles in skin lesions showed that TGF- ?1 and IL-10 were the predominant cytokines expressed (83). adaptive immune response. Immunophenotyping was used to differentiate specific types of immune cells and the proteins expressed by these cells in the adaptive immune response. Lymphocyte subsets were labeled and analyzed according to methods described previously isoindigotin (6, 18, 39C44). Lymphocytes were analyzed by a LSR flow cytometer (BD Biosciences, San Jose, isoindigotin CA, USA). Ten thousand lymphocyte-gated events isoindigotin were evaluated by histogram statistics (44). LP is the first step in a functional adaptive immune response to create effector lymphocytes necessary for T cell and B cell mediated immune responses (37). The LP response was measured using techniques optimized previously (45). Briefly, isolated viable PBLs were incubated in well plates with concanavalin A (Con A; a T-cell mitogen), lipopolysaccharide (LPS; E. coli 055:B5; a B-cell mitogen), or supplemented RPMI-1640 representing isoindigotin unstimulated wells in triplicate followed by the addition of tritiated thymidine. Cells were then harvested and assessed using a scintillation counter (Packard, Meriden, CT, USA). Antibody Titers Against Marine Bacteria Antibody titers against common marine bacteria were determined by a previously validated ELISA technique which was used to assess a general humoral response to common marine pathogens (17, 46). Cultures of were acquired from the American Type Culture Collection (ATCC, Manassas, VA, USA). Serum ELISA antibody Rabbit Polyclonal to ELOVL3 titers from individual dolphins were then expressed as antibody titers at a 1:200 serum dilution (47). Cetacean Morbillivirus Serology The genus of the Paramyxoviridae family includes the marine mammal pathogens of canine distemper virus phocine distemper virus and cetacean morbillivirus (CeMV). Other mammalian viruses in the genus include measles virus in humans and primates, pestes des petits ruminants virus in small ruminants, and rinderpest virus in large ungulates (48). A serum neutralization test for CeMV was validated and performed at the Veterinary Diagnostic Laboratory, University of Georgia, Athens, Georgia, USA. CeMV was grown in Vero cells and the test was performed as previously reported (18, 49, 50). Briefly, antibody titers were expressed as the reciprocal of the highest serum dilution that completely neutralized virus cytopathic effect. Titers 8 were considered positive for morbillivirus neutralizing serum antibody (50). Chlamydiaceae Serology comprise a large family of obligate, Gram-negative bacteria that can be the etiology of complex, multisystemic, and zoonotic disease in a wide range of domestic and wildlife species (51, 52). Interestingly, the host immune response may be ineffective in contamination isoindigotin resolution-and actually may contribute to progression of the disease (53). Ultimately, the resolution of chlamydial contamination is an immunologic challenge considering the bacteria’s unique extracellular and intracellular vegetative infectious phases (54). Clinical disease due to has not been reported in marine mammals. An indirect fluorescent antibody (IFA) test was developed and utilized for determining antibody titers to at the Avian and Wildlife Laboratory, School of Medicine, University Of Miami, Miami, Florida, USA as previously reported (19, 55). Briefly, was used for its growth characteristics and antigenic similarities which are shared with other species of Chlamydia and Chlamydophila (53, 56). The IFA method was validated with samples from confirmed cases of and reported to correlate well with the Chlamydophila elementary body agglutination serology assay and other, alternative serological methods (55, 57). titers of >1:50 were considered seropositive. Based on past studies this titer is considered indicative of recent infection, re-infection or chronic.
