Neonatal thymectomy leads to:
Tissue Thymus dependent(collection of T-lymphocytes)Thymus-independent Bursa dependent (collection of B-lymphocytes)Spleen Periaerial lymphoid collectionMalpighian corpuscle in white pulpPerifollicular regionGerminal centreMantle layerLymph nodeParacoical area between follicles in coex and medullary cords in medullaCoical folliclesGerminal centresMedullary cordsThymus-dependent regions are found grossly depleted in neonatal thymectomy (ref: Ananthanarayanan 7/e p119)
Decreased size of germinal center
Decreased size of paracoical areas
Increased antibody production
Increased bone marrow production of Lymphocytes
