Membrane Receptor # 1. Receptor Kinase: These membrane receptors contain the effector activity, such as tyrosine or serine kinase activity as an intrinsic part of the structure. The best characterised of these receptors are the protein kinase, as typified by the receptors for insulin, IGF-1, epidermal growth factor (EGF), and platelet- derived growth factor (PDGF) receptors. Each of these [...]
The following points highlight the two main types of diabetes insipidus. The types are:- 1. Central (Neurogenic) Diabetes Insipidus 2. Nephrogenic Diabetes Insipidus. Type # 1. Central (Neurogenic) Diabetes Insipidus: In central diabetes insipidus, the ADH secretion is poor. Pituitary adenomas rarely causes decrease release of ADH, but hypothalamic tumors such as craniopharyngiomas or other primary central nervous system lesions [...]
