Do you recognize this infinite series? $sum_{n=0}^infty frac 1{(1+an)^c} frac{b^n}{n!} $

I came by this infinite series
$$sum_{n=0}^infty frac 1{(1+an)^c} frac{b^n}{n!} $$
Is there some special function that can have this form?
$c$ can be assumed to be a positive integer. While $a,b$ are positive real numbers
calculus power-series special-functions

Thanks this is interesting. But I am interested in the case where a is not necessarily integer.

The sum is equal to $$ frac{1}{a^c Gamma(c)} int_{0}^{1} e^{bx} x^{(1/a)-1} log^{c-1}(1/x) , dx. $$ I am not sure if this simplifies further...

If there is any $f(x)$ that satisfies $f^{(n)}(0)=(1+an)^{-c}$, then the sum is equal to $f(b)$

When $c$ is a positive integer, the expression equals to a generalized hypergeometric function ${}_cF_cleft( alpha_1,ldots,alpha_c ; beta_1,ldots,beta_c; bright)$ where all $alpha_i = frac1a$ and and all $beta_i = frac1a + 1$.
