Mammalian cell invasion and intracellular trafficking.Smooth Brucella invasion into a cell by lipid rafts and acquisition of Rab5 and EEA1 markers – early BCV. β-1,2-glucans present in mature BCV and modification of lipid rafts. Then, the transient BCV interacts with lysosomes, T4SS is activated and it regulates intracellular trafficking from autophagosome to endoplasmatic reticulum (BCV acquires LAMP1 and Sec61β markers – late BCV – occurs only in epithelial cells). BCV acquires the endoplasmic reticulum markers (calnexin, calreticulin and Sec61-β) and the Brucella replicates. Rough Brucella organisms do not penetrate cell by lipid rafts, and therefore is exterminated.
