    Fig. 1. Experimental protocol. All trained animals carried out 4 weeks of training, 5 times per week either in MICT or HIIT. All animals performed both incremental test and grip strength at PRE, 2W and POST, while they only performed adhesive removal test and the novel object recognition test at the end of the training (in POST). During the incremental test, blood lactate was collected at every level to determine the SLT. At the end of the protocol (48 h after the last incremental test) both hippocampi and cortices were removed to perform Western blot and <t>ELISA</t> measurements.

    Article Snippet: Twenty nanograms of recombinant proBDNF (Alomone Labs) was incubated with 50 ng of recombinant MMP-9 (Calbiochem) or 50 ng of recombinant, human, inactive MMP-9 (E402A) in total volume of 20 μl.

    Activation of NMDAR (1) leads to the release of MMP-9 and BDNF (2), which might be released in its either pro-form or mature form with a propeptide. (3) tPA activates plasminogen to plasmin, which can also activate proMMP-9. (4) Plasmin and MMP-9 can extracellularly process proBDNF to mBDNF, which activates its receptor—TrkB (5). TrkB activation, together with other intracellular signaling, leads to the LTP cascade, including actin polymerization and cytoskeleton remodeling causing spine enlargement. (6) ProBDNF and BDNF propeptide, which is also co-released with mBDNF, can activate p75 TNR , leading to LTD. (7) It is possible that MMP-9 can reduce bioactive BDNF propeptide and promote a competing TrkB activation. (8) Both plasmin and MMP-9 are blocked by their inhibitors, which control their action.

    Fig. 4. Effect of MICT and HIIT programs on cortical protein levels. (a) Level of cortical mBDNF (n = 19) measured by ELISA (in pg/ml-1) in MICT, HIIT and Control groups at POST training. Level of cortical (b) TrkB (n = 20), (c) pTrkB (n = 20), (d), p757NTR (n = 19), (e) NKCC1/KCC2 ratio (n = 19), (f) KCC2 (n = 18) and (g) CTSB (n = 20) in MICT, HIIT and Control groups at POST training. Protein level measured by Western blot, was calculated as the ratio of the protein of interest divided by the protein of normalization relative to the control. The normalization protein was the α-tubulin for all the molecules except for the KCC2 which was β3-tubulin. Pictures of Western blot membranes are shown below each graph. Dashed lines were added to separate the groups. Note that the α-tubulin used for TrkB (c) was the same used for pTrkB (d), as membranes were stripped between these two quantifications. The samples derived from the same experiment and that gels/ blots were systematically processed in parallel the same day (2 gels per protein to reach a sufficient number of samples). *Significant differences in protein levels between groups. Data is expressed in mean ± SD (a–f) and in median (min to max) (g).
