Abstract
Tick-borne infections are increasing in the United States and around the world. The most common tick-borne disease in the United States is Lyme disease caused by infection with the spirochete Borrelia burgdorferi (Bb), and pathogenesis varies from subclinical to severe. Bb infection is transmitted by Ixodes ticks, which can carry multiple other microbial pathogens, including Ehrlichia species. To address how the simultaneous inoculation of a distinct pathogen impacted the course of Bb-induced disease, we used C57BL/6 (B6) mice which are susceptible to Bb infection but develop only mild joint pathology. While infection of B6 mice with Bb alone resulted in minimal inflammatory responses, mice co-infected with both Bb and the obligate intracellular pathogen Ehrlichia muris (Em) displayed hematologic changes, inflammatory cytokine production, and emergency myelopoiesis similar to what was observed in mice infected only with Em. Moreover, infection of B6 mice with Bb alone resulted in no detectable joint inflammation, whereas mice co-infected with both Em and Bb exhibited significant inflammation of the ankle joint. Our findings support the concept that co-infection with Ehrlichia can exacerbate inflammation, resulting in more severe Bb-induced disease.

Abstract
Lyme carditis, a well-established manifestation of Lyme disease, has been studied in animal models to improve understanding of its pathogenesis. This review synthesizes existing literature on these models and associated disease mechanisms. Searches in MEDLINE, Embase, BIOSIS, and Web of Science yielded 53 articles (47 mice models and 6 other animal models). Key findings include: 1) Onset of carditis correlates with spirochete localization in the heart; 2) Carditis occurs within 10 days of infection, progressing to peak inflammation within 30 days; 3) Infiltrates were predominantly composed of Mac-1+ macrophages and were associated with increases in TNF-α, IL-1 and IL-12 cytokines; 4) Resolution of inflammation was primarily mediated by lymphocytes; 5) Immune system is a double-edged sword: it can play a role in the progression and severity of carditis, but can also have a protective effect. Animal models offer valuable insights into the evolution and pathophysiologic mechanisms of Lyme carditis.

Abstract
In Borrelia burgdorferi-infected C3H-scid mice, antiserum to a differentially expressed, 37-kDa spirochetal outer-surface protein, termed arthritis-related protein (Arp), has been shown to prevent or reduce the severity of arthritis. In this study, we determined the immunoglobulin G (IgG) antibody responses to this spirochetal protein in single serum samples from 124 antibiotic-treated human patients with early or late manifestations of Lyme disease and in serial serum samples from 20 historic, untreated patients who were followed longitudinally from early infection through the period of arthritis. These 20 patients were representative of the spectrum of the severity and duration of Lyme arthritis. Among the 124 antibiotic-treated patients, 53% with culture-proven erythema migrans (EM) had IgG responses to recombinant glutathione S-transferase (GST)-Arp, as did 59% of the patients with facial palsy and 68% of those with Lyme arthritis. In addition, 75 to 80% of the 20 past, untreated patients had reactivity with this protein when EM was present, during initial episodes of joint pain, or during the maximal period of arthritis. There was no association at any of these three time points between GST-Arp antibody levels and the severity of the maximal attack of arthritis or the total duration of arthritis. Thus, after the first several weeks of infection, 60 to 80% of patients had IgG antibody responses to GST-Arp, but this response did not correlate with the severity or duration of Lyme arthritis.

Abstract
OBJECTIVE To examine the ability of bacterial lipoproteins from the spirochete Borrelia burgdorferi to cause in vivo tissue injury (arthritis). METHODS Outer surface proteins (OSPs) from B burgdorferi were used in a rat model of antigen-induced allergic arthritis. Intraarticular challenge with recombinant OspA, OspB, and OspC in nonlipidated (peptide) and lipidated forms was performed in the left knee joint; the contralateral joint received buffer as control. Inflammation was monitored by technetium scintigraphy and histology. RESULTS Nonlipidated (peptide) OspA, OspB, and OspC did not induce arthritis; the only exception was polymerized OspA, which was tested in preimmunized rats. Lipidated OspA from 2 different strains and lipidated OspC induced severe arthritis, whereas lipidated OspB failed to induce injury. A synthetic analog of the OSP lipid modification, lipopeptide Pam(3)Cys-Ser-Lys(4)-OH, either alone or coupled to bovine serum albumin, also failed to induce injury. Injury did not develop in control groups that were given the appropriate buffers or lipopolysaccharide. This showed that lipidated borrelial OSPs can be potent arthritogens but vary greatly with respect to their injury-inducing potential. The possession of a lipid modification is essential but is not sufficient to render an OSP arthritogenic. CONCLUSION This is the first study to demonstrate that individual lipoproteins from B burgdorferi can induce experimental joint injury in vivo. These results may help elucidate the pathogenesis of Lyme arthritis and, above all, underline the importance of bacterial lipoproteins as major virulence factors.

Abstract
Inbred C57bl/6 mice were challenged with high-passage Borrelia afzelii, Borrelia garinii and Borrelia burgdorferi sensu stricto and tested for antigen specific T-cell response in vitro. Sonicated preparations of washed spirochetes were potent cell activators, capable of stimulating polyclonal proliferation after 72h of culture while increasing the incubation time up to 120h provoked specific cell-mediated response. Isolated murine spleocytes previously sensitized to B. burgdorferi sensu lato but not those from control mice could be induced for antigen-specific proliferation in vitro, as revealed by [3H]thymidine incorporation assay, Moreover, in mice presensitized to B. burgdorferi sensu lato, detectable cell-mediated response could be induced only with antigen preparations derived from a corresponding strain but not with those obtained from other Borrelia genospecies. The current study emphasises that the B. burgdorferi antigen-specific response may also be expected in different genospecies infections in men.

Abstract
Inbred C57BL/6 mice were challenged with Borrelia afzelii, Borrelia garinii and Borrelia burgdorferi sensu stricto and tested for antigen-specific T-cell response in vitro. The sonicated preparations of in vitro grown spirochetes were capable of stimulating polyclonal proliferation and specific cell-mediated response, depending on duration of the cell culture. Murine splenocytes previously sensitized to B. burgdorferi sensu lato (s.l. ), but not those from control mice, could be induced for antigen-specific proliferation in vitro. Moreover, detectable cell-mediated response could be induced only with antigen preparations derived from a corresponding strain but not with those obtained from other Borrelia genospecies as revealed by the [(3)H]thymidine incorporation assay. The current study considers that the strict B. burgdorferi s.l. antigen-specific response may also be expected in infections in humans and contributes to the explanation of the frequently poor antibody- and cell-mediated immune response observed in patients diagnosed with Lyme disease.

Abstract
Lyme disease is a treatable and curable infectious disease that can be diagnosed with relative confidence with attention to the details of the syndrome and proper use of serologic testing to confirm the clinical diagnosis. Lyme disease should not be a "diagnosis of exclusion," made on the basis of isolated serologic reactivity or because of the presence of symptoms compatible with Lyme disease. The pathogenesis of chronic complaints following infection with B. burgdorferi is often unclear, but such persistent complaints should not automatically be ascribed to ongoing infection. There is no proven role for long-term antibiotics or combination regimens.

Abstract
Previous studies have demonstrated that both Ixodes scapularis saliva and Borrelia burgdorferi antigens modulated lymphokines and monokines in vitro. The studies presented here were designed to delineate the role of I. scapularis and B. burgdorferi in modulation of the host immune response in vivo. Infestation of C3H/HeJ mice with infected I. scapularis resulted in an up regulation of IL-4 as early as 8 days after tick infestation, while the levels of T helper cell type 1 (TH1) cytokines, interleukin-2 (IL-2) and gamma interferon (IFN-gamma), were significantly decreased by days 10 to 12. In contrast, the cytokine profile of BALB/c mice exposed to infected nymphal ticks resulted in only transient alterations in IL-4, IL-2, and IFN-gamma production throughout a 12-day period postinfestation. Although the IL-10 level was elevated in both C3H/HeJ and BALB/c mice infested with infected nymphal ticks, no significant difference in the levels of IL-10 was noted between the mouse strains. Flow-cytometric analysis demonstrated increases in the numbers of splenic B-cell and CD4+ lymphocytes in C3H/HeJ but not BALB/c mice exposed to infected ticks. Cell depletion experiments with C3H/HeJ mice demonstrated that CD4+ cells were the sole producers of IFN-gamma and IL-10 while both CD4+ and CD8+ splenocytes contributed to the production of IL-2 and IL-4. These findings suggest that B and CD4+ splenocytes are activated, increase in number, and produce a polarized TH2 response in C3H/HeJ mice exposed to infected I. scapularis. Given that C3H/HeJ mice are susceptible to Lyme disease and the initial TH2 polarization is not evident in BALB/c mice, effective control of this response may have ramifications for spirochete transmission in vivo.

Abstract
p35 and p37 are Borrelia burgdorferi genes encoding 35 and 37 kDa proteins. The gene products were identified by differential screening of a B. burgdorferi expression library with sera from B. burgdorferi infected- and B. burgdorferi-hyperimmunized mice. Northern blot and RT-PCR analyses confirmed that these genes were selectively expressed in vivo. ELISA, using P35 and P37, showed that infected mice (5 of 5, 100%) and patients (31 of 43, 72%) with Lyme borreliosis developed P35 or P37 antibodies. Mice developed peak IgG titers to P35 and P37 within 30 days, followed by decline. Mice given both P35 and P37 antisera were protected from challenge with 10(2) B. burgdorferi, and P35 and P37 antisera also afforded protection when administered 24 hr after spirochete challenge. The use of in vivo-expressed antigens such as P35 and P37 represents a new approach for Lyme disease serodiagnosis and for understanding the role of B. burgdorferi-specific immune responses in host immunity.

Abstract
Lyme disease, caused by Borrelia burgdorferi, causes a multisystem inflammatory ailment, although the precise means of tissue damage are not well understood. It is clear that the organism is present at the site of inflammation in many organs and that many of the features of the illness are relieved by antibiotic therapy. A complex interaction between spirochete and immune systems of a number of mammalian hosts, in human disease and animal models, has been described. It is clear that T cells and macrophages are intimately associated with the pathogenesis of arthritis and that immune mechanisms are involved in other aspects of disease. Inflammation directed at persistence of Borrelial antigens is a plausible explanation for persisting arthritis. Autoimmunity based on molecular mimicry may play a role in the pathogenesis of Lyme disease. Humoral immunity plays a protective role, prompting interest in vaccine development. Significant variation in certain of the outer surface proteins suggests that multiple proteins, peptides, or chimeric vaccines may be needed to provide a sufficiently broad humoral protective response.

Abstract
Plasmid DNA encoding the outer surface lipoprotein A (OspA) of Borrelia burgdorferi under the control of either strong eukaryotic/viral or its own bacterial promoter was injected intramuscularly (m. tibialis anterior) or intradermally into BALB/c and AKR/N mice. OspA-specific antibodies and OspA-reactive T helper 1 cells (Th1) were induced only with those plasmids containing the ospA structural gene including its own regulatory control region immediately upstream. In the absence of the ospA promoter, no or only marginal immune responses to OspA were obtained, even when strong eukaryotic promoter/enhancer elements were present. Together with the finding that the ospA promoter is active in a mouse B-lymphoma line, the data suggest that spirochetes are able to express at least part of their genes in the mammalian environment. Mice previously vaccinated with the relevant ospA plasmid DNA were protected against subsequent experimental challenge with a virulent strain of B. burgdorferi, as measured by the appearance of antibodies to a prominent protective epitope (LA-2) and the failure to re-isolate spirochetes from ear biopsies. In addition, C.B-17 severe-combined immunodeficient mice could be protected against infection by passive transfer of immune sera from ospA plasmid DNA-inoculated normal mice. Protective LA-2-related antibody titers obtained after repeated immunization persisted for 200 days and longer. This simple procedure of immunization using plasmid DNA consisting of a prokaryotic gene under the control of its own promoter holds great promise for the development of alternative subunit vaccines against bacterial infections, including Lyme disease. In addition, the availability of this novel prokaryotic promoter element now allows the study of the basis for the differential expression of bacterial genes in prokaryotic and eukaryotic environments.

Abstract
Plasmid DNA-based vaccination is an efficient way to evoke various forms of protective immunity in laboratory animals. Our previous experiments have shown that mice immunized with either plasmid DNA encoding the outer surface lipoprotein A (pOspA) of Borrelia burgdorferi or the respective lipoprotein (Lip-OspA) produce protective antibodies against subsequent challenge with virulent spirochetes. In the present study, we compared the specificity and function of T cells generated in AKR/N mice previously immunized to either pOspA or Lip-OspA. T cell populations derived by either of the two protocols consistently responded by proliferation in vitro to one (residues 186-203; B4) out of a panel of 27 overlapping 20-mer peptides spanning the entire OspA molecule of strain ZS7. B4 was shown to express allele-specific ligand motifs for I-Ek. Most of the other peptides produced variable and much less pronounced or marginal proliferative T cell responses. T cells reactive to B4 as well as to some minor epitopes were CD4+CD8- T cells which produced IFN-gamma but no detectable IL-4 upon antigen stimulation in vitro. Priming of AKR/N mice with B4 but not with inactive peptides of OspA led to an enhanced production of IgG antibodies, mainly of the IgG1 isotype, including those to a prominent protective epitope (LA-2) upon subsequent challenge with Lip-OspA or intact spirochetes. The data demonstrate that both plasmid DNA and protein immunization with OspA results in T cell responses with specificity for a dominant OspA epitope and suggest that priming of mice with immunodominant peptides accelerates the appearance of protective antibodies in vivo. The identification of T helper cell epitopes relevant for the induction of protective antibodies will also facilitate the design of more potent vaccines against Lyme disease.
