In vitro- and in vivo-polarised absorptive epithelia (enterocytes) are considered
to be non-phagocytic towards bacteria with invasive pathogenic strains relying on
virulence factors to 'force' entry. Here, we report a serendipitous discovery
that questions these beliefs. Thus, we uncover in well-established models of
human small (Caco-2; TC-7) and large (T84) intestinal enterocytes a
polarization-dependent mechanism that can transfer millions of bacteria from the
basal to apical compartment. Antibiotic-protection assays, confocal imaging and
drug inhibitor data are consistent with a transcellular route in which
internalized, basolateral-membrane enclosed bacteria are trafficked to and across
the apical surface. Basal-to-apical transport of non-pathogenic bacteria (and
inert beads) challenged the idea of pathogens relying on virulence factors to
force entry. Indeed, studies with Salmonella demonstrated that it's entry-forcing
virulence factor (SPI-I) was not required to enter via the basolateral surface
but to promote another virulence-associated event (intra-enterocyte
accumulation).
