Figura 1 – Representação esqu<strong>em</strong>ática da resposta febril.<br />

Todas as vias <strong>de</strong> indução <strong>de</strong> febre são bastante complexas. A<br />

compreensão dos <strong>de</strong>talhes <strong>de</strong> sua indução, interação com diversos sist<strong>em</strong>as,<br />

novas moléculas pirogênicas e <strong>de</strong> como estas moléculas interag<strong>em</strong> <strong>de</strong>ntro do<br />

sist<strong>em</strong>a, b<strong>em</strong> como novas maneiras <strong>de</strong> bloquear o sist<strong>em</strong>a, são úteis não<br />

somente para se enten<strong>de</strong>r a febre per se (e consequent<strong>em</strong>ente como controlá-<br />

la mais a<strong>de</strong>quadamente durante processos inflamatórios e infecciosos), mas<br />

também para se enten<strong>de</strong>r como se processa a comunicação entre o sist<strong>em</strong>a<br />

imune e o sist<strong>em</strong>a nervoso central.<br />
