Loss of Immunization-Induced Epitope-Specific CD4 T-Cell Response following Anaplasma marginale Infection Requires Presence of the T-Cell Epitope on the Pathogen and Is Not Associated with an Increase in Lymphocytes Expressing Known Regulatory Cell P. Clin Vaccine Immunol. 2015;22:742-53 pubmed publisher
    ..As hypothesized, the induction of T-cell exhaustion occurred only following infection with A. marginale, which did not correlate with an increase in either CD4(+) CD25(+) FoxP3(+) T cells or any γδ T-cell subset examined. ..

    ..These ISS may be involved in host immune modulation during protozoal infection and may be useful as vaccine adjuvants. ..
  4. Brown W, McElwain T, Palmer G, Chantler S, Estes D. Bovine CD4(+) T-lymphocyte clones specific for rhoptry-associated protein 1 of Babesia bigemina stimulate enhanced immunoglobulin G1 (IgG1) and IgG2 synthesis. Infect Immun. 1999;67:155-64 pubmed

  5. Brown W, Palmer G, Lewin H, McGuire T. CD4(+) T lymphocytes from calves immunized with Anaplasma marginale major surface protein 1 (MSP1), a heteromeric complex of MSP1a and MSP1b, preferentially recognize the MSP1a carboxyl terminus that is conserved among strains. Infect Immun. 2001;69:6853-62 pubmed
    ..The data provide a basis for determining whether selected MSP1a CD4(+) T-lymphocyte epitopes and selected MSP1a and MSP1b B-lymphocyte epitopes presented on the same molecule can stimulate a protective immune response. ..
  6. Brown W, Shkap V, Zhu D, McGuire T, Tuo W, McElwain T, et al. CD4(+) T-lymphocyte and immunoglobulin G2 responses in calves immunized with Anaplasma marginale outer membranes and protected against homologous challenge. Infect Immun. 1998;66:5406-13 pubmed

    Brown W, Norimine J, Knowles D, Goff W. Immune control of Babesia bovis infection. Vet Parasitol. 2006;138:75-87 pubmed
    ..The availability of an annotated B. bovis genome will, for the first time, enable identification of non-immunodominant proteins that may stimulate protective immunity. ..
  8. Brown W, Zhu D, Shkap V, McGuire T, Blouin E, Kocan K, et al. The repertoire of Anaplasma marginale antigens recognized by CD4(+) T-lymphocyte clones from protectively immunized cattle is diverse and includes major surface protein 2 (MSP-2) and MSP-3. Infect Immun. 1998;66:5414-22 pubmed
    ..Our results provide a rationale for identifying Th cell epitopes conserved among different strains of A. marginale for inclusion in a nucleic acid or recombinant protein vaccine. ..
  9. Zhang B, Cavallaro A, Mody K, Zhang J, Deringer J, Brown W, et al. Nanoparticle-Based Delivery of Anaplasma marginale Membrane Proteins; VirB9-1 and VirB10 Produced in the Pichia pastoris Expression System. Nanomaterials (Basel). 2016;6: pubmed publisher
    ..Overall this study demonstrates the potential of self-adjuvanting silica vesicle formulations to address current deficiencies in vaccine delivery applications. ..

    ..This indicates highly adapted strategies of Anaplasma spp. to both suppress protective immune responses and evade those that do develop. However, conserved subdominant antigens are potential targets for immunization. ..
