    An inverse relation between endogenous levels of glucocorticoids and splenic mass and cellularity was detected. Decreased endogenous corticosterone blood levels result in an increased number of immunoglobulin-secreting cells in the spleen, a fact that cannot be attributed only to the expansion of the lymphoid cell mass. The opposite phenomenon was observed in animals with high corticosterone blood levels, which showed reduced numbers of immunoglobulin-secreting cells. It is concluded that endogenous glucocorticoid levels contribute to the control of B cell activity and possibly to the interaction of these cells with other immunologic cells.

    Regulation of Hematopoietic Stem Cells

    All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

    Cushing Syndrome II: Pathophysiology

    Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
