Abstract
Intrahippocampal pilocarpine microinjection (H-PILO) induces status epilepticus (SE) that can lead to spontaneous recurrent seizures (SRS) and neurodegeneration in rodents. Studies using animal models have indicated that lectins mediate a variety of biological activities with neuronal benefits, especially galectin-1 (GAL-1), which has been identified as an effective neuroprotective compound. GAL-1 is associated with the regulation of cell adhesion, proliferation, programmed cell death, and immune responses, as well as attenuating neuroinflammation. Here, we administrated GAL-1 to Wistar rats and evaluated the severity of the SE, neurodegenerative and inflammatory patterns in the hippocampal formation. Administration of GAL-1 caused a reduction in the number of class 2 and 4 seizures, indicating a decrease in seizure severity. Furthermore, we observed a reduction in inflammation and neurodegeneration 24 h and 15 days after SE. Overall, these results suggest that GAL-1 has a neuroprotective effect in the early stage of epileptogenesis and provides new insights into the roles of exogenous lectins in temporal lobe epilepsy (TLE).

Multiple alignment and similarity among GAL-1 from different organisms. (A) Multiple sequence alignment of galectin-1 sequences from Human, Rat, Conger myriaster (congerin-1 and -2), and Cinachyrella sp obtained with MAFFT. Chemical similarity color scheme and conservation logos are depicted at the top of the graphical representation constructed with the msa R package. (B) Distance matrix from multiple sequence alignment that depicts dissimilarity index for GAL-1 sequence pairs calculated using R package. (PNG 696 kb)
Supplementary Fig. 3
Total seizures number and time of Racine´s classes 3 and 5 during SE. GAL-1+PILO group presented a tendency to increase the number of class 5 seizures compared VEH+PILO (A), as well as pre-treatment with GAL-1 decreased seizures time in class 3 (C and D). We analyzed the number at classes 3 and 5 of Racine’s scale for window (10 min) in VEH + PILO and GAL-1 + PILO to observe the severity of seizures with more details. P < 0.05. *, ** and *** compared with VEH + PILO; unpaired t test or two-way ANOVA with Tukey’s post-hoc test (PNG 744 kb)
