Division of labor during primary humoral immunity

Division of Labor during Apical Hook Formation.

Division of labor during trunk neural crest development.

Neural crest cells, the migratory precursors of numerous cell types including the vertebrate peripheral nervous system, arise in the dorsal neural tube and follow prescribed routes into the embryonic periphery. While the timing and location of neural crest migratory pathways has been well documented in the trunk, a comprehensive collection of signals that guides neural crest migration along the...

Humoral immunity in cardiomyopathy.

Sera from patients with heart disease were examined by single sandwich indirect immunofluorescence for the presence of antibodies to human heart muscle. Endocardial biopsy specimens were also examined by direct immunofluorescence for deposition of antibodies in vivo. No consistent or specific abnormality was found in the biopsy specimens or sera of patients with congestive cardiomyopathy. The p...

Corticosterone selectively decreases humoral immunity in female eiders during incubation.

Immunity is hypothesized to share limited resources with other physiological functions and this may partly account for the fitness costs of reproduction. Previous studies have shown that the acquired immunity of female common eider ducks (Somateria mollissima) is suppressed during their incubation, during which they entirely fast. Corticosterone was proposed to be an underlying physiological me...
