Maybe something like this?
ax = gca();
set(ax, ...
'XLim',[0.7 4.5], ...
'YLim',[0 40], ...
'XTick',1:4, ...
'YTick',0:5:40, ...
'GridColor','r', ...
'XGrid','on', ...
'YGrid','on');
ytl = get(ax,'YTickLabels');
ytl(2:2:end) = {''};
set(ax,'YTickLabels',ytl);

If you have R2018b or later, the easiest solution would likely be the xline and yline functions.
x = 0:5;
y = randi(40, size(x));
figure
plot(x, y)
xline(1:5,'-r')
yline(5:5:40,'-r')
yticks(0:10:40)
.
