Taken together, these findings indicate that stimulation of A1 and A2 adenosine receptors mediates a differential modulation of [Ca 2+ ] i signalling elicited by P2 purinoceptors. Some studies have concluded that astrocytes could be divided into neurotoxic so-called A1 astrocytes (induced by reactive microglia) and neuroprotective so-called A2 astrocytes [19, [27] [28][29]. In 2012, researchers resolved that ambiguity when they identified two distinct types of reactive astrocytes, which they called A1 and A2. In the presence of LPS , a component found in the cell walls of bacteria, they observed that resting astrocytes somehow wind up getting transformed into A1s, which are primed to produce large volumes of pro-inflammatory substances. Differential modulation of ATP-induced calcium signalling by A1 and A2 adenosine receptors in cultured cortical astrocytes Susanna Alloisio IntroductionAdenine-based purines are ubiquitous extracellular signalling molecules, which in mammals are involved in the functional regulation of virtually all tissues and organs (Ralevic & Burnstock, 1998).

Extracellular Glu concentration was measured 5 h after addition of 100 μM Glu with 300 μM TBHA (a1, a2) or 1 mM DHK (b1, b2 2007-02-26 This video describes the structure and function of astrocytes.

However, injured-ACM was unable to improve OPC maturation. Neuroinflammation and ischemia induced two different types of reactive astrocytes, termed “A1” and “A2,” respectively. This terminology parallels the “M1” and “M2” macrophage nomenclature, which has also been applied to microglia in the CNS. Microglia, the resident immune cells within the CNS, are extremely heterogeneous. The associated gene (pan reactive, A1 or A2) on the right side of each panel.

In mice, too, A1 astrocytes consumed only half the normal amount of synaptosomes. Co-culture with A1 astrocytes proved fatal for RGCs, cortical neurons, embryonic spinal motor neurons, and myelin-producing oligodendrocytes. A1 cells killed a quarter of dopaminergic neurons and slowed the differentiation of oligodendrocyte precursors. Increased astrocytes were mainly A1-like astrocytes; however, the number of A2-like type decreased. In cell culture, OPC differentiation was interrupted under mimic chronic ischemia, but improved after astrocyte-conditioned medium (ACM) was added.

Annexin A1 (ANXA1), also called lipocortin 1 or calpactin 2, belongs to the annexin family, which undergoes Ca 2+-dependent binding to phospholipids (1, 2). The expression of ANXA1 is induced by glucocorticoids , and ANXA1 potently inhibits phospholipase A2 .

Astrocyte reactivity is disease- and stimulus-dependent, adopting either a proinflammatory A1 phenotype or a protective, anti-inflammatory A2 phenotype.

An equally important question is how or why the proportion of A1 and A2 astrocytes change during neuroinflammation; in most cases the change is from helpful to the harmful variety. Astrocyter är de största av gliacellerna och namnet kommer av att de är stjärnformade.
