He kills Voldemort's snake, a.k.a. one of the horcruxes. He also gets tortured.
I'm not sure what happened to Dean, but Neville went on to marry Hannah Abbott and he is the Herbology teacher at Hogwarts.
Death Eaters try to trap her, and she escapes and goes into hiding. She fights in the final battle.
Neville was tortured by Death Eaters, specifically by Bellatrix Lestrange, in the seventh book of the Harry Potter series.
Neville becomes an auror, before quiting to become the proffessor of herbology at Hogwarts, and marries Hannah Abbott.
Voldemort forces a burning Sorting Hat onto Neville's hat, Neville as a worthy Gryffindor (as Harry was in the second book) pulls the sword out of the Sorting Hat.
Hannah Abott is said to have married Neville Longbottomand is the new landlady of the Leaky Caldron! :-)

Coralie Neville was born on August 7, 1924, in New Zealand.
