Resumo

Atualmente, as pesquisas estão avançando com o laser de baixa intensidade (LBI), em células do sistema nervoso central, com o objetivo de avaliar os benefícios dessa terapia em distúrbios neurológicos como Alzheimer, acidente vascular cerebral, isquemia, epilepsia, entre outros. O objetivo deste estudo foi verificar os efeitos biomoduladores e bioestimuladores do LBI em cultura de células neurais. Laser de diodo comprimento de onda λ = 830 nm, potência de 40 mW, em modo contínuo, foi aplicado sobre a linhagem celular 9L/lacZ com densidades de energia de 0,5 a 3J/cm2. A análise foi realizada 24 horas após a irradiação, os resultados de viabilidade celular mostraram diferença entre os grupos controle e irradiado. Quanto à ocorrência de apoptose, nenhuma manifestação significativa foi observada entre grupo controle comparado ao irradiado (P = 0,9956); houve diferença significativa entre apoptose e morte por necrose entre os grupos controle e tratado (P <0,001). No ensaio de cometa não foram observadas diferenças estatisticamente significativas. Com relação ao objetivo de avaliar se LBI promove ativação precoce de apoptose ou proliferação de células 9L/lacZ em diferentes densidades de energia do laser de diodo infravermelho, observamos ocorreu aumento no número de células neurais, destacando a ação de biomodulação. Além disso, o LBI não promoveu a ativação da morte celular programada - apoptose e não apresentou qualquer indicação de dano ao DNA pelo ensaio de cometa. Os resultados deste estudo são indicativos de que o laser no infravermelho próximo tem uma interação positiva com as células neuronais.
