Nervous System
Damage Check
Why is it that humans and
,other mammals are left per-
/--- manently paralyzed or other-
wise handicapped by injuries
to the central nervous system,
while fish and other "lower"
\_ life forms can repair such
injuries and resume normal
lives?
A study led by Professor
Michal Schwartz of the
We i zmann Institute of
• Science provides an explana-
tion that links the mam-
malian inability to repair cen-
tral nerve damage with evolu-
tion — and offers hope for
developing an effective treat-
ment for injuries to the spinal
cord and other parts of the
central nervous system.
Evolution allowed mam-
D
mals to have complex brains,
capable of acquiring new
knowledge throughout a life-
• time. But, according to
Professor Schwartz, along
' with this asset came a disad-
vantage: the brain and the rest
of the central nervous system •
lost their self-healing ability,
`–iwhich exists in lower verte,
braces. Professor Schwartz says
this loss probably occurred as
a result of the critical need to
protect the brain from remod-
• eling by the immune system:
while immune cells normally
help to heal damaged tissue,
their access to the brain
would disrupt the complex
;land dynamic neuronal net-
works that build up during an
individual's lifetime.
Generally, when tissue
damage occurs, immune cells
known as macrophages swarm
• to the injured site, where they
remove damaged cells and
release substances that pro-
mote healing. The central ner-
-
- -)vous system in mammals is an
exception in this regard: when
damaged, it is not effectively
