<p>Dear all</p>
<p>We had a good experience working with AM amastigotes for drug testing. We find out that AM amastigote are a better model for drug testing than promastigote. there were a close relation between In vivo and In vitro when we used AM model, but there were not relation between promastigote and in vivo experience.</p>

<p class="MsoNormal"><span style="font-size: 11.0pt; font-family: 'Calibri','sans-serif'; color: #1f497d;">Axenic amastigotes (Ax) are much more than “stressed-out promastigotes”. We (and others) have shown they are very similar (although not identical) to macrophage-derived amastigotes (Am) in terms of global mRNA and protein expression levels. While it would obviously be better to work with Am, it is often technically difficult due to low numbers and contamination with macrophage RNA and protein. In addition, it is my contention that the time taken to isolate Am from the macrophages makes them “stressed-out amastigotes”, which are less physiological relevant than Ax. We need to approach this discussion from a position of knowledge and data (i.e. understanding exactly which genes are expressed differently in Am and Ax) than belief. Hopefully, we will be able to publish the results of our RNA-seq studies comparing promastigotes, axenic amastigotes and macrophage-derived amastigotes (without purification) in the not too distant future.<!-- o ignored --></span></p>

Many of us use axenics and swear by them, others are skeptical, others will accept what's inside a macrophage, still others only want amastigotes isolated from something with a fur. I believe we should come to some sort of common language and interpretation. I am somewhere in the middle myself, preferring to do things in macrophages whenever possible.</span><span style="color: black;"><!-- o ignored --></span></p>
