Mwachitsanzo, m'matenda monga Alzheimer's ndi Parkinson's, kusintha kumawonedwa mu ma neuron ndi ma cell a glial omwe angakhudze ntchito yawo yanthawi zonse. Kuphunzira kwa ma cell a dongosolo lamanjenje ndikofunikira kuti mumvetsetse matendawa ndikupanga mankhwala othandiza.

Mwachidule, mawonekedwe a ma cell a dongosolo lamanjenje ndi gawo lochititsa chidwi la maphunziro lomwe limatithandiza kumvetsetsa bwino momwe magwiridwe antchito ndi mawonekedwe akulu amanjenje athu. Kupyolera mu nkhaniyi, tafufuza mitundu yosiyanasiyana ya maselo omwe amapanga dongosolo ili, monga neurons ndi maselo a glial, komanso bungwe lawo m'madera osiyanasiyana monga ubongo ndi msana.

Ma cell a minyewa, okhala ndi zowonjezera zotchedwa axon ndi dendrites, amagwira ntchito yofunika kwambiri pakufalitsa ndi kukonza chidziwitso mkati mwa dongosolo lamanjenje. Kuphatikiza apo, ma cell a glial amatenga gawo lofunikira pothandizira ndi kusunga ma neurons, komanso kuwongolera chilengedwe cha neuronal.

Chofunika kwambiri, kuphunzira za kapangidwe ka ma cell a dongosolo lamanjenje sikuti kumangotithandiza kumvetsetsa momwe thupi lathu limagwirira ntchito, komanso kumakhudzanso kafukufuku ndi chitukuko chamankhwala a matenda amisempha. Kudziwa zofunikira za ma cell a mitsempha ndi gulu lawo kumatithandiza kuthana ndi zovuta monga Alzheimer's, Parkinson's and multiple sclerosis.

Pomaliza, mawonekedwe a ma cell a dongosolo lamanjenje ndi mutu wovuta koma wofunikira kuti timvetsetse momwe ubongo umagwirira ntchito komanso dongosolo lamanjenje lonse. Pamene kafukufukuyu akupita patsogolo, ndizosangalatsa kuganizira za mwayi womwe umatsegulira kuti ukhale wathanzi. ndi ubwino wa anthu.
