Some experts support the theory of panspermia, the idea that life on Earth, and perhaps other places in the Universe, results from the distribution of organic, bacterial, and other material traveling in and on asteroids, comets, meteorites, and the tons of cosmic dust that float out of the sky every day. For these scientists, strict planetary protection mechanisms are overrated, because organic material is constantly hitchhiking through the galaxy. And it is true, some of that dull dust on your roof, sidewalk, or car parked outside is star dust..

These results would suggest that low levels of CXCL12 and recognition of self peptides presented by self MHC on endothelial cells allows efficient migration of Tregs whereas higher levels of CXCL12 may promote tumour metastases and lead to fugetaxis of the Tregs leading to an even worse prognosis.In conclusion recognition of cognate antigen presented by endothelium enhances antigenspecific transmigration of CD8 and Regulatory T cells. This study therefore reports a novel mechanism for T cell subset infiltration into tumours where high avidity CD8 T cells require recognition of cognate tumour antigen presented on tumour endothelium in the context of MHC class I and conversely regulatory T cell infiltration into tumours depends on the repertoire of self peptides presented on tumour endothelium in the context of MHC class II. Alteration of antigen presentation or MHC expression on tumour endothelium therefore represents a mechanism whereby T cell infiltration can be altered to re direct anti tumour immune responses..

But such critique does not enable understanding of how coherency is accomplished between different modes of reason.
