    Abstract A secondary local and splenic cell-mediated immune response was observed and compared to the primary response. Previous studies have demonstrated cell-mediated immunity (CMI) by lymphocytes from bronchopulmonary washings and have shown that its appearance is to a large extent inedpendent of splenic CMI. This study evaluated the secondary as compared to the primary response, with respect to both cellular and humoral immune responses. Guinea pigs were immunized with influenza virus vaccine either nasally or parenterally, booster immunizations were given by the same route, and animals were killed at various times after immunization or booster. The inhibition of macrophage migration was used to assess CMI. As in previous studies, local application of antigen led to mainly local appearance of CMI, whereas parenteral immunization led to mainly systemic CMI. Both pulmonary and splenic lymphocytes showed an inhibition of macrophage migration that appeared 2 to 3 days sooner after the booster, as compared to the primary immunization. There was no evidence, however, for the earlier production or increased amount of antibody in the bronchial secretions in the boosted animals. The results suggest that pulmonary as well as splenic T lymphocytes exhibit memory, but that pulmonary B lymphocytes do not.

    Abstract Unlabelled: Immune-mediated lung injury is a hallmark of lower respiratory tract illness caused by respiratory syncytial virus (RSV). STAT4 plays a critical role in CD4+ Th1 lineage differentiation and gamma interferon (IFN-γ) protein expression by CD4+ T cells. As CD4+ Th1 differentiation is associated with negative regulation of CD4+ Th2 and Th17 differentiation, we hypothesized that RSV infection of STAT4-/- mice would result in enhanced lung Th2 and Th17 inflammation and impaired lung Th1 inflammation compared to wild-type (WT) mice. We performed primary and secondary RSV challenges in WT and STAT4-/- mice and used STAT1-/- mice as a positive control for the development of RSV-specific lung Th2 and Th17 inflammation during primary challenge. Primary RSV challenge of STAT4-/- mice resulted in decreased T-bet and IFN-γ expression levels in CD4+ T cells compared to those of WT mice. Lung Th2 and Th17 inflammation did not develop in primary RSV-challenged STAT4-/- mice. Decreased IFN-γ expression by NK cells, CD4+ T cells, and CD8+ T cells was associated with attenuated weight loss and enhanced viral clearance with primary challenge in STAT4-/- mice compared to WT mice. Following secondary challenge, WT and STAT4-/- mice also did not develop lung Th2 or Th17 inflammation. In contrast to primary challenge, secondary RSV challenge of STAT4-/- mice resulted in enhanced weight loss, an increased lung IFN-γ expression level, and an increased lung RSV-specific CD8+ T cell response compared to those of WT mice. These data demonstrate that STAT4 regulates the RSV-specific CD8+ T cell response to secondary infection but does not independently regulate lung Th2 or Th17 immune responses to RSV challenge.
    Importance: STAT4 is a protein critical for both innate and adaptive immune responses to viral infection. Our results show that STAT4 regulates the immune response to primary and secondary challenge with RSV but does not restrain RSV-induced lung Th2 or Th17 immune responses. These findings suggest that STAT4 expression may influence lung immunity and severity of illness following primary and secondary RSV infections.

    Abstract Rabbits were sensitized with either a soluble protein antigen (BSA) or a particulate thermophilic actinomycete antigen (Micropolyspora faeni) via the respiratory route, followed by monitoring of sequential morphologic changes and the humoral plus cellular immunologic response. Primary respiratory tract sensitization with BSA resulted in a humoral anti-BSA response, Arthus and delayed skin reactivity, and in some cases specific antigen-induced alveolar macrophage migration inhibition, all in the absence of pulmonary lesions. Lesions characterized by mild multifocal perivascular mononuclear cell infiltrates in the lungs developed only after secondary BSA aerosol challenge. In contrast to these findings, "primary" respiratory tract sensitization with M. faeni particulate antigen in saline solution resulted in the gradual development of extensive and progressive pulmonary interstitial and alveolar mononuclear cell infiltrates. These lesions were uniformly associated with specific serum precipitating antibody and delayed skin reactivity. Alveolar macrophage migration was significantly inhibited by Micropolyspora faeni in virtually of these animals. These results, while not excluding a primary irritant effect or Type II or III alergic tissue injury, suggest a role for delayed (cell-mediated) hypersensitivity in the pathogenesis of particulate actinomycete-induced pulmonary lesions. They also indicate that primary immunization with soluble purified protein antigens via the respiratory route can lead to systemic humoral and cell-mediated immunity without production of pulmonary lesions.
