The third term models the diffusion process of antibodies in the tissue, at a rate of D F, and the last term describes the flux of antibodies between the LN and the tissue, at a rate of α F, in which F L is the concentration of antibodies released by plasma cells in the LN (11).
This result was unexpected, as one could have hypothesized that the increased cellular density, higher degree of compaction and ECM accumulation would have interfered with the diffusion of the antibodies into the spheroid and their subsequent effects.
The immunological events and neuronal mechanisms underlying these observations need to be explored further, but one possibility is that the early stage represents diffusion of serum antibodies into the cortical grey matter, whereas the later stage results from secondary expansion of the immunological repertoire within the intrathecal compartment acting on subcortical neurons.
To do this, we performed layered loading of the pipette by backfilling the antibody-containing solution (45 µg/mL) over antibody-free solution, to allow recording of channel activity prior to the diffusion of the antibody to the pipette tip.
This method allows for an adequate diffusion of the antibody but it decreases the preservation of the material due to light fixation, and, therefore, it decreases the quality of the image [16].
In vivo diffusion capability of TS1 have been demonstrated earlier [30, 31, 50, 51] and these small areas of necrotic tissue created by177Lu-DOTA-Tyr3-octreotate by177Lu-DOTA-Tyr3-octreotate by177Lu-DOTA-Tyr3-octreotate by177Lu-DOTA-Tyr3-octreotateached by diffusion of treatmentntibody over short distasces in vivo.
These findings suggest diffusion of the locally produced antibodies from the synovium to the periphery.
The accurately defined thickness of the tissue slices (200μm) allows a smooth diffusion of nutrients, drugs, and antibodies.
Diffusion of primary and secondary antibodies was limited by overlying the solutions with a piece of parafilm as described in the Protocols section.
