How to make xtick where there is a tick label in bold?

How to make the xtick mark where I have a label in bold (as shown in attached figure).

Here is the code I use to generate the figure:

years = [1979:1:2021];

figure(1);

hold on;
axis on;
grid on;
box on;

plot(years,TS_Mask,'LineWidth',3,'Color','black')

yline(M,'-k','LineWidth',2);      %yline(M,'-k','mean');
yline(M+S,'--k','LineWidth',2);   %yline(M+S,'--k','mean + 1*std');
yline(M-S,'--k','LineWidth',2);   %yline(M-S,'--k','mean - 1*std');
p1=plot(positiveAnomaly,TS_Mask(find(TS_Mask >= M+S)),'^');
p1.MarkerSize = 12;
p1.MarkerFaceColor = 'black';
p1.MarkerEdgeColor = 'black';
p2=plot(negativeAnomaly,TS_Mask(find(TS_Mask <= M-S)),'v');
p2.MarkerSize = 12;
p2.MarkerFaceColor = 'black';
p2.MarkerEdgeColor = 'black';

p2007 = plot(2007,TS_Mask(29),'o','MarkerFaceColor','black','MarkerEdgeColor','black','MarkerSize',12);
p2012 = plot(2012,TS_Mask(34),'o','MarkerFaceColor','black','MarkerEdgeColor','black','MarkerSize',12);

xlabel('years','FontSize',24)
ylabel('SLP [hPa]','FontSize',24)

set(gca,'Fontsize',18);

xticks([1978:1:2022]);
xticklabels({'','','1980','','','','','1985',...
    '','','','','1990','','','','','1995','','','','','2000',...
    '','','','','2005','','','','','2010','','','','','2015',...
    '','','','','2020',''.''})
xtickangle(0);

xlim([1978 2022]);
gcf;

I want to add bold tick mark in x where I have the x tick labels i.e. 1980, 1985, 1990, etc.

How can I do this?

Thank you

xticklabels({'','','\bf 1980','','','','','\bf 1985',...
  '','','','','\bf 1990','','','','','\bf 1995','','','','','\bf 2000',...
  '','','','','\bf 2005','','','','','\bf 2010','','','','','\bf 2015',...
  '','','','','\bf 2020',''.''})

I would take a different approach, of setting xticks every 5, and setting MinorTicks every 1, and not specifying the tick labels. Instead, set

ax = gca; ax.xAxis.TickLabelFormat = '\bf %d';

Thank you for your answer. I am not looking to put the xticklabels in bold but rather to have the xticksmark where I have labels be bold/ thicker than the other ticks for better vizualisation. Do you know how to do this? Thank you

Do not xticks all the values. xticks the ones you want in bold, and set the minorticks to take care of everything else
