Non-specific humoural immunity response in latent and tertiary syphilis.

Non-specific humoural immunity response in latent and tertiary syphilis.

Leptin regulates energetic tradeoffs between body fat and humoural immunity.

Mounting an immune response requires a relatively substantial investment of energy and marked reductions in energy availability can suppress immune function and presumably increase disease susceptibility. We have previously demonstrated that a moderate reduction in energy stores via partial surgical lipectomy (LIPx) impairs humoural immunity of Siberian hamsters (Phodopus sungorus). Here we tes...

Transfer of humoural immunity over two generations in urban pigeons.

Maternal antibodies (MatAb) are known to provide passive protection early in life for young vertebrates but their effects on the development of offspring immune response across generations are still unknown. Here, we investigated the effects of antigen exposure (keyhole limpet haemocyanin, KLH) experienced by urban pigeon (Columba livia) females on the amount of antigen-specific antibodies (Abs...

Immunity in syphilis.

There are those who view the study of immunity in syphilis and the development of an effective immunizing agent as problems of academic interest only since the advent of penicillin therapy. There are also those who believe, particularly since the worldwide resurgence of syphilis occurring after 1957, that therapeutic and case-finding advances such as have occurred with syphilis represent only h...

Immunity in syphilis. Studies in active immunity.

Support for the concept of the development of immunity during the course of syphilis is avaiable in the literature. In experimental syphilis in rabbits, some immunity is present approximately 3 weeks after infection with Treponema pallidum. Resistance to re-infection increases to a maximum at approximately 3 months after infection. Termination of this state by penicillin treatment within this 3...
