Figure 9. α/βNrxn3–Nlgn3Δ synaptic signals do not regulate VGT3+ inhibitory synapse transmission.

Figure 9.

(A–D) Effect of pre- and postsynaptic overexpression (OE) of βNrxn3(±AS4) and Nlgn3Δ, respectively, on unitary inhibitory synaptic transmission in organotypic slice cultures prepared from NrxnTKO/VGT3/RFP mice. (E–H) Effect of pre- and postsynaptic OE of αNrxn3(±AS4) and Nlgn3Δ, respectively, on unitary inhibitory synaptic transmission. (A and E) Averaged sample unitary inhibitory postsynaptic current (uIPSC) traces. Summary of uIPSC amplitude (B and F), paired-pulse ratio (C and G), and connectivity (D and H). Numbers of cell pairs: βNrxn3+AS4, βNrxn3-AS4, αNrxn3+AS4, and αNrxn3-AS4 at VGT3+ synapses (eight pairs/three mice, 9/3, 5/3, and 11/3). The number of tested slice cultures is the same as that of cell pairs. Mann–Whitney U-test.
