X. Belles, INTERACTIONS BETWEEN CORPORA ALLATA, FAT-BODY AND OVARY IN INSECT REPRODUCTION - WHICH CONTROLS WHICH, Netherlands journal of zoology, 45(1-2), 1995, pp. 152-156
The classical model describing the endocrinology of vitellogenesis inv
olves the juvenile hormone (JH) produced by the corpora allata (CA), w
hich induces the synthesis of vitellogenin (Vg) in the fat body, which
is then incorporated into developing oocytes. However, exceptions and
special regulatory loops have been reported in different insects, thu
s leading to a more complicated picture. In spite of the great diversi
ty encountered, it may be possible to reach a unified scheme of the in
terplay between CA, fat body and the ovary, where homeostasis is accom
plished by autoinhibition and short and long-loop feedback mechanisms.
