Immune response and anti-microbial peptides expression in malpighian
tubules of Drosophila melanogaster is under developmental regulation.
C) Spleen, showing marked lymphoid depletion and lymphocyte necrosis in the Malpighian
body and vacuolation of reticulocytes in the red pulp (arrow).
Histopathological investigation: In the control and GE groups, the Malpighian
corpuscles were spherical and each consists of a bunch of blood capillaries called the glomerulus, which surrounded by Bowman's capsule.
Histological examination of the mass showed fibrous tissue lined by the malpighian
epithelium with predominantly orthokeratotic hyperkeratosis.
Patchy parakeratosis, epidermal hyperplasia, absence of granular layer, accumulation of neutrophil in Malpighian
layer, elongation of rete ridges and dilated capillaries in superficial dermis 2.
The following characters are diagnostic for the Class Diplura: antennae many-segmented, flagellar segments provided with muscles, compound eyes and ocelli absent, tarsi I segmented, abdomen with lateral styliform appendages on most or all of the pre-genital segments, body distally with paired cerci of variable form, terminal median filament absent, tracheal system present, malpighian
tubules vestigial or absent.
Age and physiological maturity is determined by changes in the reproductive system, as well as somatic cells (fat body, cuticle, malpighian
tubules, trachea, etc.), or external factors (e.g., "wear and tear") (Tyndale-Biscoe 1984; Hayes & Wall 1999; Klowden 2007).
Silk is produced in one of three positions on the insect body: in the labium (as modified "salivary" glands), Malpighian
tubules, or in a variety of dermal glands.
The endosymbiont Wolbachia was also detected in the head, muscles, Malpighian
tubules, ovaries, and testes of Culex pipiens and Aedes albopictus .
Control kidney section showed the renal corpuscles (Malpighian
corpuscles) within renal cortex (C).
It includes cystic cavities lined by a ciliated respiratory epithelioma, a gastric mucosa surrounded by soft muscle bundles, a regular Malpighian
epithelioma, a mature nervous tissue, pancreatic tissue, and hepatic tissue (Figure 5).
This alters the properties of adhesion cell molecules, producing intraepithelial blisters between the Malpighian
