The replication then takes place in the cytoplasm after the virus is in the cell and the virion is uncoated. The virion is then assembled and released from the host cell.The genome is arranged so that both of the ends contain the genes responsible for evading the defenses from the immune system of the host which is only activated in the extracellular portion. These receptors are able to be stopped by cytokine and chemokine secretion by blocking the cytokine and chemokine found extracellularly. This is the process responsible for attachment and entry of the virion into the host cell. Because of the large size of the genome, it makes the virus more likely and capable to fight back against the immunes system defenses. Out of all of the poxviruses, CPXV has the most cytokine responses that fight back against the immune system. It encodes cytokine receptors such as TNF, CrmB, CrmC, CrmD, and CrmE proteins. Another set of receptors that CPXV have are lymphotoxins such as IL-1ß, IFN-y, IFN 1, β-chemokines, and IL-18. However, not all of the receptors of CPXV are still not known. CPXV also encodes four tumor necrosis factors (TNF) and lymphotoxin which are the biggest group of homologous receptors for the virus. These receptors play a crucial role that are involved with the immune system. CPXV has two different types of inclusion bodies. All of the poxviruses have basophilic inclusions also called B-type inclusion bodies.
Also, males tend to be more affected as Alport syndrome is X-linked in most cases. In IgA nephropathy, episodes of frank hematuria are more common, and a family history is less common.A kidney biopsy is the only way to diagnose thin basement membrane disease. It reveals thinning of the glomerular basement membrane from the normal 300 to 400 nanometers (nm) to 150 to 250 nm. However, a biopsy is rarely done in cases where the patient has isolated microscopic hematuria, normal kidney function, and no proteinuria. The prognosis is excellent in this setting unless the clinical manifestations progress, as occurs in most males and some females with Alport syndrome and many patients with IgA nephropathy. Treatment
Most patients with thin basement membrane disease need only reassurance. Indeed, this disease was previously referred to as "benign familial hematuria" because of its usually benign course. Angiotensin converting enzyme inhibitors have been suggested to reduce the episodes of hematuria, though controlled studies are lacking. Treating co-existing hypercalciuria and hyperuricosuria will also be helpful in reducing hematuria.The molecular basis for thin basement membrane disease has yet to be elucidated fully; however, defects in the gene encoding the a4 chain of type IV collagen have been reported in some families. Prognosis
Overall, most people with thin basement membrane disease have an excellent prognosis. Some reports, however, suggest that a minority might develop hypertension.Thin basement membrane disease may co-exist with other kidney diseases, which may in part be explained by the high prevalence of thin basement membrane disease.
