“…However, adaptation to low temperature did lead to an improvement in the respiratory burst which would imply improved bacterial killing ability . This greater e#ectiveness of phagocytosis at low environmental temperature was reported in tench (Tinca tinca) by Collazos et al (1994). Lastly, macrophages isolated from rainbow trout (Oncorhynchus mykiss) kept and cultured at low temperatures were responsive to macrophage activating factor and showed a higher relative increase in respiratory burst activity compared with their counterparts cultured at higher temperatures (Hardie et al, 1994).…”

“…It has been postulated that the nonspecific immune reactions are less temperature-dependent than specific immune reactions (Collazos et al, 1994). In this study, small temperature di#erences (3 C) had a significant e#ect on the number of activated circulating granulocytes.…”

“…Low temperatures appear to increase the efficacy of certain nonspecific immune responses, including cytotoxic cell lytic activity (Le Morvan et al, 1995), phagocyte respiratory burst (Dexiang and Ainsworth, 1991;Collazos et al, 1994) and macrophage response to activating factor and burst activity (Le Morvan et al, 1997). Thus, there is evidence that nonspecific immunity may respond to cold stress relatively quickly and protect the organism from further damage by a pathogen until cold-temperature suppression of specific immunity is overcome.…”

SUMMARYThe ability to heal superficial wounds is an important element in an organism's repertoire of adaptive responses to environmental stress. In fish,motile cells termed keratocytes are thought to play important roles in the wound-healing process. Keratocyte motility, like other physiological rate processes, is likely to be dependent on temperature and to show adaptive variation among differently thermally adapted species. We have quantified the effects of acute temperature change and thermal acclimation on actin-based keratocyte movement in primary cultures of keratocytes from four species of teleost fish adapted to widely different thermal conditions: two eurythermal species, the longjaw mudsucker Gillichthys mirabilis (environmental temperature range of approximately 10-37°C) and a desert pupfish, Cyprinodon salinus (10-40°C), and two species from stable thermal environments, an Antarctic notothenioid, Trematomus bernacchii(-1.86°C), and a tropical clownfish, Amphiprion percula(26-30°C). For all species, keratocyte speed increased with increasing temperature. G. mirabilis and C. salinus keratocytes reached maximal speeds at 25°C and 35°C, respectively, temperatures within the species' normal thermal ranges. Keratocytes of the stenothermal species continued to increase in speed as temperature increased above the species'normal temperature ranges. The thermal limits of keratocyte motility appear to exceed those of whole-organism thermal tolerance, notably in the case of T. bernacchii. Keratocytes of T. bernacchii survived supercooling to -6°C and retained motility at temperatures as high as 20°C. Mean keratocyte speed was conserved at physiological temperatures for the three temperate and tropical species, which suggests that a certain rate of motility is advantageous for wound healing. However, there was no temperature compensation in speed of movement for keratocytes of the Antarctic fish, which have extremely slow rates of movement at physiological temperatures. Keratocytes from all species moved in a persistent,unidirectional manner at low temperatures but at higher temperatures began to take more circular or less-persistent paths. Thermal acclimation affected the persistence and turning magnitude of keratocytes, with warmer acclimations generally yielding more persistent cells that followed straighter paths. However, acclimation did not alter the effect of experimental temperature on cellular speed. These findings suggest that more than one temperature-sensitive mechanism may govern cell motility: the rate-limiting process(es) responsible for speed is distinct from the mechanism(s) underlying directionality and persistence. Keratocytes represent a useful study system for evaluating the effects of temperature at the cellular level and for studying adaptive variation in actin-based cellular movement and capacity for wound healing.
