IL17-Producing γδ T Cells May Enhance Humoral Immunity during Pulmonary Pseudomonas aeruginosa Infection in Mice

The host acquired immune response, especially the humoral immunity, plays key roles in preventing bacterial pneumonia in the lung. Our previous research demonstrated that interleukin 17-producing γδ T cells (IL17-γδ T cells) have a protective effect on the early innate immune response during acute pulmonary Pseudomonas aeruginosa infection. However, whether IL17-γδ T cells also play a role in h...

IL-17-producing γδ T cells enhance bone regeneration.

Immune responses are crucial not only for host defence against pathogens but also for tissue maintenance and repair after injury. Lymphocytes are involved in the healing process after tissue injury, including bone fracture and muscle damage. However, the specific immune cell subsets and mediators of healing are not entirely clear. Here we show that γδ T cells produce IL-17A, which promotes bone...

Involvement of IL‐17A‐producing TCR γδ T cells in late protective immunity against pulmonary Mycobacterium tuberculosis infection

INTRODUCTION Interleukin (IL)-17A is a cytokine originally reported to induce neutrophil-mediated inflammation and anti-microbial activity. The CD4+ T cells, which produce IL-17A, have been well characterized as Th17 cells. On the other hand, IL-17A-producing TCR γδ+ T cells have been reported to participate in the immune response at an early stage of infection with Listeria monocytogenes and M...

Induction of Specific Humoral Immune Response in Mice against a Pseudomonas aeruginosa Chimeric PilQ/PilA Protein

Background: Pseudomonas aeruginosa, an opportunistic pathogen, is a common cause of healthcare-associated infections in immunocompromised individuals. The rapid emergence of multidrug-resistant strains has made P. aeruginosa infections progressively difficult to treat. In this study we evaluated the effect of a chimeric protein containing a P. aeruginosa PilQ fragment and the PilA disulfide loo...

Pyrorubrin-producing Pseudomonas Aeruginosa.

Pyrorubrin, a red pigment produced by some Pseudomonas aeruginosa cultures, was first described by Meader, Robinson, and Leonard (Amer. J. Hyg. 5:682, 1925). The object of this note is to record the incidence of pyrorubrinforming strains in clinical material and the more frequent occurrence of these strains in urinary isolates of P. aeruginosa. During an investigation in which different typing ...
