What is O4 a marker for?
What is O4 a marker for?
Oligodendrocyte Marker O4 is an antigen on the surface of oligodendrocyte progenitors (1, 2). It has been commonly used as the earliest recognized marker specific for the oligodendroglial lineage (3-8).
What does Olig2 stain for?
Olig2 (and Olig1) antibodies stain OPCs and mature oligodendrocytes. Olig2 also stains a subset of astrocytes, although it is down-regulated postnatally with time such that by P21 in mice, that subset of astrocytes no longer expresses Olig2.
What rank is O4?

| O4 | Major | Major |
| O5 | Lieutenant Colonel | Lieutenant Colonel |
| O6 | Colonel | Colonel |
What is O4?
O-4, the pay grade for the following officer ranks in the U.S. uniformed services: Major (United States) in the Army, Air Force, and Marine Corps. Lieutenant Commander in the Navy, Coast Guard, Public Health Service Commissioned Corps, and NOAA Commissioned Officer Corps.
What are oligodendrocytes quizlet?
Oligodendrocytes. A CNS glial cell that forms myelin sheaths. It forms the myelin that surrounds many axons in the CNS. Each cell forms one segment of myelin for several adjacent axons.
What do oligodendrocytes do?
Oligodendrocytes are the myelinating cells of the central nervous system (CNS). They are the end product of a cell lineage which has to undergo a complex and precisely timed program of proliferation, migration, differentiation, and myelination to finally produce the insulating sheath of axons.
What rank is O4 in the Navy?
O-4 Lieutenant Commander – U.S. Navy Ranks Lieutenant Commander is the fourth commissioned officer’s rank in the U.S. Navy, and is equivalent to the rank of Major in the other Armed Services. Lieutenant Commanders typically serve as mid-ranking officers in the excutive and command divisions of Navy vessels.
What rank is O4 in the army?
Military Grade & Rank

| O6 | Colonel | Colonel |
| O7 | Brigadier General ⭐ | Brigadier General ⭐ |
Can there be O4?
As O has 2 valence electron it can form 2 single or 1 double bond . Ex H2O. But it cannot form O4 as O do not have d-orbital therefore it cannot accomodate more than 8 electrons but Sulphur can because it have vacant d-orbital.
Is O4 unstable?
However, the atomic-level details of O4-Aβ-oligomer interaction are largely unknown. We found that the Aβ(17-42) trimer is unstable without O4, whereas its structural stability is greatly enhanced with O4.
What is the most important function of the oligodendrocytes?
Oligodendrocytes are specialized glial cells that wrap themselves around neurons present in the CNS. Oligodendrocytes are primarily responsible for maintenance and generation of the myelin sheath that surrounds axons. They also participate in axonal regulation and the sculpting of higher order neuronal circuits [51].
What happens when oligodendrocytes are damaged?
Thus, neurotransmitter receptors play an important role in the normal life of oligodendrocytes. Furthermore, if oligodendrocytes become damaged and the myelin sheath is destroyed, the action potential is reduced in velocity or ceases altogether, leading to physical or mental disability.
What is oligodendrocyte marker O4?
Oligodendrocytes are myelinating cells within the central nervous system (CNS) that form the myelin sheath of axons to support rapid nerve conduction. Oligodendrocyte Marker O4 is an antigen on the surface of oligodendrocyte progenitors.
What is O4 marker used for?
Oligodendrocyte Marker O4 is an antigen on the surface of oligodendrocyte progenitors (1, 2). It has been commonly used as the earliest recognized marker specific for the oligodendroglial lineage (3-8). Schachner, M. et al. (1981) Dev. Biol. 83 :328.
What does O4 mean in immunology?
Oligodendrocyte Marker O4 is an antigen on the surface of oligodendrocyte progenitors. O4 has been commonly used as the earliest recognized marker specific for the oligodendroglial lineage. The monoclonal antibodies A2B5, O4, and O1 are frequently used to define distinct stages in the maturation of oligodendrocyte progenitors.
What is the difference between o2o-antigens and O4?
O-Antigens are expressed on oligodendrocytes during differentiation and on mature oligodendrocytes in the central nervous system. O4 is formed during postnatal development and is a marker for cell bodies and processes of oligodendrocytes types I and II. O4 is expressed in pro-oligodendrocytes, however, it is not found on O-2A-progenitor cells.
