Plasmodial

Définitions de « plasmodial »

Plasmodial - Adjectif

• (Biologie) Relatif aux plasmodes, organismes unicellulaires caractérisés par une masse de cytoplasme mouvante.

  Lorsque les conditions deviennent défavorables, les mouvements de la masse plasmodiale s'interrompent; celle-ci se condense et se transforme en quelques heures en un zoosporange, générateur de zoospores.

• (Biologie) Concernant le genre Plasmodium, protozoaire parasite responsable du paludisme.

  Dans leur étude approfondie des organismes pathogènes, les chercheurs ont découvert des caractéristiques alarmantes concernant la résistance plasmodiale aux traitements antipaludiques.

• To assess the compositional stoichiometry of plasmodial proteasome subunits, we analyzed the relative abundance of proteasome subunits by using a label-free quantitative approach based on the normalized spectral abundance factor (NSAF), which is particularly compatible with shotgun proteomics25. As shown in Fig. 3A, most proteasome components were found present with similar abundance, except two ATPase base subunits (Rpt2 and Rpt5) with higher abundance and two subunits (Rpn13 and β2) with low abundance. In accordance, low recovery of subunit Rpn13 has been reported in affinity purifications of human proteasomes23,24.

• Moreover, they demonstrated that stimulator of interferon genes (STING) and TANK-binding kinase 1 (TBK1) — which are both downstream effectors of the DNA-induced type I IFN response — are essential for innate immune activation by plasmodial DNA, and cytoplasmic ATTTTTAC motif-containing ODNs formed a complex with STING and TBK1. Further studies showed that IFNβ expression in response to AT-rich cytoplasmic DNA is induced via interferon-regulatory factor 3 (IRF3) and IRF7.

• “This work may give us a clue to the role of topo VI in plasmodial parasites and suggests that the enzyme could be a target for anti-malarial drugs in the future. In plants too, topo VI could have potential as a target for herbicides,” he added. 

• While it sounds like fiction, this scenario does happen (minus Steve McQueen et al) during periods of wet weather on mulched beds, in the woods, and other places with abundant organic matter. Of course there are some key qualifications to the above description. The blob, called a plasmodial slime mold, is slimy, but not a mold. What it is, precisely, may be still up for debate.
