Eosinophils contain specific granules, which are the dominant population of cytoplasmic granules in these cells. These granules are characterized by a centrally located crystalloid electron-dense core surrounded by an outer less dense matrix, storing preformed cationic proteins, cytokines, chemokines, and growth factors. Additionally, eosinophils possess other unique organelles such as eosinophil sombrero vesicles (EoSVs), which play a crucial role in transporting granule-derived products. The granules in eosinophils contain a variety of immune mediators that are released through different secretory processes like classical and compound exocytosis, piecemeal degranulation, and cytolysis. These granules are essential for eosinophil-mediated responses and are involved in the release of toxic compounds to combat microbes and contribute to various eosinophilic disorders.How is vein formed in retina?4 answers
Veins in the retina are formed through a combination of vasculogenesis and angiogenesis processes stimulated by physiological hypoxia. During development, blood vessel formation in the retina occurs through vasculogenesis and angiogenesis. The expression of vascular endothelial growth factor (VEGF) by astrocytes and Muller cells plays a crucial role in inducing the formation of retinal vessels in response to hypoxia caused by increased neuronal activity. Endothelial cell migration over an astrocytic template, guided by filopodial extensions and R-cadherin, contributes to the characteristic honeycomb pattern of vessel formation in the superficial layer of the retina. Additionally, VEGF-A secreted by astrocytes guides vascular sprouting and promotes retinal angiogenesis, while CTGF is involved in promoting fibrovascular membrane formation during retinal vascular repair in adult mice.What markers are used for human Retina tissue labelling?5 answers
Markers commonly used for labeling specific cells in human retina tissue include protein kinase C alpha (PKC alpha), Islet-1, glycine, Go alpha, recoverin, glutamate transporter-1, PKC beta, CD15, calbindin, and Calcium-binding protein 5 (CaB5). These markers help identify various types of bipolar cells in the central retina, distinguishing between ON and OFF bipolar cells based on their anatomical location and marker content. Additionally, immunochemical markers are available for detecting photoreceptors, bipolar cells, amacrine cells, horizontal cells, Muller cells, and retinal pigment epithelial cells in the retina of humans and other mammals. The use of these markers aids in understanding retinal development, disease progression, and potential therapeutic interventions by visualizing specific cell populations and their distribution within the retina.What markers are used for human Retina tissue labelling in diabetic?5 answers
Markers used for human retina tissue labeling in diabetic conditions include apoptotic and antiapoptotic molecules, as well as metabolic markers. Apoptotic markers such as caspase-3, Fas, and Bax are expressed in ganglion cells of diabetic retinas, indicating vulnerability. Antiapoptotic markers like Bcl-2, ERK1/2, and survivin are also observed in diabetic retinas, suggesting a protective response. Additionally, antiapoptotic molecules Cox-2, Akt, and Mcl-1 are expressed in ganglion cells of both diabetic and nondiabetic retinas, while proapoptotic molecule Bad is upregulated in response to diabetes-induced injury. Metabolites like 2-Piperidone and 12-hydroxy-arachidonic acid are used as combined markers in blood samples for diagnosing retinopathy in diabetic patients, aiding in early detection. These markers play crucial roles in understanding the pathophysiology of diabetic retinopathy.How do temperature, humidity, and precipitation affect the physical and mechanical properties of Tectona grandis?5 answers
